Single spin- and chiral-glass transition in vector spin glasses in three-dimensions

Results of Monte Carlo simulations of XY and Heisenberg spin glass models in three dimensions are presented. A finite size scaling analysis of the correlation length of the spins and chiralities of both models shows that there is a single, finite-temperature transition at which both spins and chiralities order.Comment: 5 pages, 5 figures.

Extended skyrmion lattice scattering and long-time memory in the chiral magnet Fe1−x_{1-x}Cox_xSi

Small angle neutron scattering measurements on a bulk single crystal of the doped chiral magnet Fe$_{1-x}$Co$_x$Si with $x$=0.3 reveal a pronounced effect of the magnetic history and cooling rates on the magnetic phase diagram. The extracted phase diagrams are qualitatively different for zero and field cooling and reveal a metastable skyrmion lattice phase outside the A-phase for the latter case. These thermodynamically metastable skyrmion lattice correlations coexist with the conical phase and can be enhanced by increasing the cooling rate. They appear in a wide region of the phase diagram at temperatures below the $A$-phase but also at fields considerably smaller or higher than the fields required to stabilize the A-phase

Electronic Structure of Cu_(1-x)Ni_xRh_2S_4 and CuRh_2Se_4: Band Structure Calculations, X-ray Photoemission and Fluorescence Measurements

The electronic structure of spinel-type Cu_(1-x)Ni_xRh_2S_4 (x = 0.0, 0.1, 0.3, 0.5, 1.0) and CuRh_2Se_4 compounds has been studied by means of X-ray photoelectron and fluorescent spectroscopy. Cu L_3, Ni L_3, S L_(2,3) and Se M_(2,3) X-ray emission spectra (XES) were measured near thresholds at Beamline 8.0 of the Lawrence Berkeley Laboratory's Advanced Light Source. XES measurements of the constituent atoms of these compounds, reduced to the same binding energy scale, are found to be in excellent agreement with XPS valence bands. The calculated XES spectra which include dipole matrix elements show that the partial density of states reproduce experimental spectra quite well. States near the Fermi level (E_F) have strong Rh d and S(Se) p character in all compounds. In NiRh_2S_4 the Ni 3d states contribute strongly at E_F, whereas in both Cu compounds the Cu 3d bands are only ~1 eV wide and centered ~2.5 eV below E_F, leaving very little 3d character at E_F. The density of states at the Fermi level is less in NiRh_2S_4 than in CuRh_2S_4. This difference may contribute to the observed decrease, as a function of Ni concentration, in the superconducting transition temperature in Cu_(1-x)Ni_xRh_2S_4. The density of states of the ordered alloy Cu_(1/2)Ni_(1/2)Rh_2S_4 shows behavior that is more ``split-band''-like than ``rigid band''-like.Comment: 7 pages of text, 11 trailing figures, updated to fix faulty postscript in Fig.

ABSTRACT ANALYSIS OF CONSUMER BUYING PREFERENCES IN BROILER MEAT AT TRADITIONAL MARKET IN MANADO CITY (CASE STUDY OF THE "PINASUNGKULAN KAROMBASAN MARKET"). The goals of this study was to analyze consumer preference and attitude on attribute variation of broilers at the traditional market in Manado. Study was conducted at the Pinasungkulan market, Karombasan Manado on February 2019. Survey method was used  by deep interview supported by questionnaire. Samples were defined by accidental sampling method involving fifty respondents. The primer and secondary data were used in this study and analyzed by Chi-Square and Multi attribute Fishbein analysis. The Chi-Square analysis indicated that all attributes studied were significantly different. This was meaning that there were differences of consumers preference on broilers. On the basis of Multi attribute Fishbein analysis indicated that all broiler attribute were considered by consumers in making decision of buying broilers. Broilers were became consumer preference significantly at the Pinasungkulan Market, meaning that there was difference of consumer preference on broiler attributes. Sequences of broiler attribute from the highest consideration to the lowest consideration were meat color, skin color, meat smell, skin tenderness and meat weight. Consumer attitude on broiler meat attributed in decision of buying meat of broilers was broiler meat color.  Keywords: Broiler, consumer preferenc

District of Suluun Tareranis the area located in the regency ofSouth Minahasa. The majority of SuluunTareran district communities areworking household farmers and minorityof this community are working as civilservants, private employees andbussinesman. The communityconsumption of meat and eggs dependslargely on the income earned. Thetendency of increased consumption ofmeat and eggs depends also on theincreased income of the community inthis regency. The higher the income thehigher also the deman tendency toconsume meat and egg. The problem ofthis study is that are the consumptions ofmeat and eggs in the District SuluunTareran influenced by householdincome? The purpose of this study wasto evaluate the amount of meat and eggconsumptions of the household and todetermine the effect of householdincome on the consumption of meat andeggs at the district of Suluun Tareran.This research has been conducted in thedistrict of Suluun Tareran involving thetotal sample of 74 respondent ofhouseholds. Data collection of thisresearch was conducted during 2 monthsusing survey method. The data waereanalysed using simple regressionanalysis to determine the effect ofincome on consumption of meat andeggs. The results showed that theaverage household income was Rp2,558,050 per month. Meat and eggconsumption have not reached the newtarget of 7.7 kg and 4.1 kg per capita peryear, respectively; to fulfill theappropriate food and nutrition workrecommended by widyakarya in 2004.The analysis showed that the householdincome significantly affect theconsumption of meat and eggs in theDistrict of Suluun TareranKeywords: Meat-egg consumption,Household Income,Suluun Tareran distric

Universality of the helimagnetic transition in cubic chiral magnets: Small angle neutron scattering and neutron spin echo spectroscopy studies of Fe1−x_{1-x}Cox_xSi

We present a comprehensive Small Angle Neutron Scattering (SANS) and Neutron Spin Echo Spectroscopy (NSE) study of the structural and dynamical aspects of the helimagnetic transition in Fe$_{1-x}$Co$_x$Si with $x$ = 0.30. In contrast to the sharp transition observed in the archetype chiral magnet MnSi, the transition in Fe$_{1-x}$Co$_x$Si is gradual and long-range helimagnetic ordering coexists with short-range correlations over a wide temperature range. The dynamics are more complex than in MnSi and involve long relaxation times with a stretched exponential relaxation which persists even under magnetic field. These results in conjunction with an analysis of the hierarchy of the relevant length scales show that the helimagnetic transition in Fe$_{1-x}$Co$_x$Si differs substantially from the transition in MnSi and question the validity of a universal approach to the helimagnetic transition in chiral magnets
