Contribution of s-d Interaction to the Internal Magnetic Field in Heusler Alloys

Spin echoes and their external magnetic field effects have been observed on Heusler alloys, Cu_2MnAl, Cu_2MnIn and Cu_2MnSn at 4.2°K. The sign of the internal magnetic field at nuclei of the constituent elements has been determined to be negative, and on the basis of the R-K-K-Y interaction semiquantitative agreement between calculated and observed internal magnetic fields has been obtained in Cu_2MnAl, Cu_2MnIn and Cu_2MnSn. The spectra for Cu, Mn and Sn in Cu_2MnSn, In in Cu_2MnIn and Al in Cu_2MnAl have been observed for the first time

NMR Study of Quasicrystal Al_<70>Pd_<20>T_<M10> Alloy (T_M : Cr, Mn, Fe and Co)

^Al-, ^Mn- and ^Co-NMR measurements have been made on quasicrytalline phases of the Al_Pd_T_ alloy (T_M : Cr, Mn, Fe and Co) in the temperature range between 5K and room temperature. There is no marked temperature dependence on peak shift and line width of either ^Al- or ^Co- NMR spectra except ^Al- and ^Mn- spectra in the Al_Pd_Mn_. However, the peak shift of these spectra depends upon the constituent transition element. For the Al_Pd_Mn_, the negative ^Al- Knight shift and line broadening at low temperatures indicate that there exist two classes of Mn atoms, magnetic and nonmagnetic ones

Developments from enquiries into the learnability of the pattern languages from positive data

AbstractThe pattern languages are languages that are generated from patterns, and were first proposed by Angluin as a non-trivial class that is inferable from positive data [D. Angluin, Finding patterns common to a set of strings, Journal of Computer and System Sciences 21 (1980) 46–62; D. Angluin, Inductive inference of formal languages from positive data, Information and Control 45 (1980) 117–135]. In this paper we chronologize some results that developed from the investigations on the inferability of the pattern languages from positive data

The Effect of Atomic Ordering on the Magnetic Properties of Fe-Al Alloys

The effect of atomic ordering on the magnetic properties of Fe-Al alloys has been studied for the specimens with different compositions. The so-called "double-Curie point" phenomenon has been studied at a magnetic field strength of 242 Oe : the behavior of the magnetization in this temperature range is different from that observed at lower magnetic filed strengths, and Pal and Tarnoczi\u27s interpretation, which is based on the demagnetizing filed caused by the formation of a finely dispersed paramagnetic Fe_3Al ordered phase, cannot apply to this case. There is some evidence that the Curie temperature of FeAl ordered phase is higher than that of Fe_3Al ordered phase, and at high Al concentrations both of these temperatures are lower than the Fe_3Al-FeAl transformation temperature. The difference in the paramagnetic behavior between the FeAl ordered phase and disordered phase has been observed and discussed

Morphological analysis of the retina in salt-loaded KK-Ay mice, obese and type 2 diabetic model

Retinopathy, one of the microvascular complications in diabetes, can cause blindness. Salt-loading is known to exacerbate microvascular damage and may affect retinopathy. In this study, we investigated the effect of salt loading on early lesions of diabetic retinopathy. Male C57BL/6 and KK-Ay mice were salt-loaded with 1% sodium chloride (NaCl)-containing drinking water for 12 weeks. In addition, to determine the effects of high fat and high sucrose, a high fat/high sucrose diet was also fed to the 1% NaCl-loaded group of mice of both strains. Retinal thickness was measured at an arbitrary location from the optic nerve disc, and thinning of the retina was observed in KK-Ay mice compared to C57BL/6 mice. Salt-loading caused retinal thinning in C57BL/6 mice, but not in KK-Ay mice. In KK-Ay mice, the effect of salt-loading may have been masked by the effects of obesity and diabetic status during this experimental period. There was also a small effect of QF on the retina, suggesting that dietary components other than salt loading may affect retinopathy
