Anomalous magneto-optical Kerr hysteresis loops in Fe0.25_{0.25}TaS2_{2}

We have performed magneto-optical Kerr spectroscopy measurements on intercalated transition-metal dichalcogenide Fe$_{0.25}$TaS$_{2}$ in the polar Kerr geometry as a function of temperature, magnetic field, and wavelength. The Kerr angle exhibits pronounced peaks at $\sim$775 nm (1.6 eV) and $\sim$515 nm (2.4 eV), which we attribute to spin-dependent interband optical transitions arising from states in the vicinity of the Fermi energy. Below the ferromagnetic transition temperature (165 K), we observe strongly wavelength- and magnetic-field-dependent Kerr signal. At a fixed wavelength, the magnetic-field dependence of the Kerr angle shows a clear hysteresis loop, but its shape sensitively changes with the wavelength. We propose a model that takes into account contributions from domain walls, which allowed us to derive a mathematical expression that successfully fits all the observed hysteresis loops.Comment: 6 pages, 6 figure

THE COSTS AND BENEFITS OF EDUCATION – A BRIEF REVIEW

Information on the profitability of investment in the educational system of Romania is now almost inexistent, so the assertion that education is, at least in words, a national priority, which, exploited, can generate sustainable economic growth and social welfare, is not founded now on any economic data. Next we perform an analysis of the current global research findings in the field, emphasizing, where necessary, the problems remained unsolved.costs of education, benefits of education, the efficiency of the investment in education

RESEARCH REGARDING THE ROLE OF CONTINUOUS FORMATION OF THE EMPLOYEES IN ORDER TO INCREASE THE COMPETITIVENESS OF ORGANISATIONS IN SUCEAVA COUNTY

Defence mechanism, competitiveness is seen as a means of ensuring the survival of organizations. Are companies and even countries that speak of competitiveness in order to survive to the onslaught of globalization, new entrants and low profit margins. The studies are showing that all organisation are recognising the role and importance of human resources in ensuring its competitiveness. The present paper will try to analyse the role of employees' formation and to establish their importance in increasing the competitiveness, based on information offered by the companies from Suceava County.human resources, continuous formation, training programs, competitiveness

OBJECTIVES AND PARTICULARITIES OF DECISIONS IN THE CONTEXT OF CORPORATE GOVERNANCE

Corporate governance means the overall driving of the entire organization byaccepting all internal components, which work together, which eventually will be integrated in themanagement, and implemented to the risk management within the organization and financialmanagement system and internal control, including internal audit. At this time of globalization andharmonization, the accounting profession acts for the image that it deserves, fulfilling a criticalrole. Harmonization, convergence of accounting systems in service, currently must be made by themost trained professionals, under conditions of total transparency. Presently, the global economy,the influx of investment and cross-border operations in particular of the large enterprise groupsexert a strong influence on the accounting profession.accounting systems, decision processes, corporate governance, financial information.

THE POLICY OF PRICES AN IMPORTANT ELEMENT IN SUBSTANTIATION OF PENETRATION STRATEGY IN NEW MARKET SEGMENTS

Pricing policy aims to determine the price of goods and services sold by the organization. These figures have an impact over the turnover that must be higher to the total expenses for the enterprise to make profits. Therefore, it is important to know thecorporate strategy, accounting information, the need of information, users of accountancy’s products

Type-I superconductivity in ScGa3 and LuGa3 single crystals

We present evidence of type-I superconductivity in single crystals of ScGa3 and LuGa3, from magnetization, specific heat, and resistivity measurements: low critical temperatures Tc = 2.1-2.2 K; field-induced secondto first-order phase transition in the specific heat, critical fields less than 240 Oe; and low Ginzburg-Landau coefficients {\kappa} approx 0.23 and 0.30 for ScGa3 and LuGa3, respectively, are all traits of a type-I superconducting ground state. These observations render ScGa3 and LuGa3 two of only several type-I superconducting compounds, with most other superconductors being type II (compounds and alloys) or type I (elemental metals and metaloids).Comment: 5 pages, 6 figure

THE ACCOUNTING OF ASSET LIQUIDATION IN DISSOLVING COMPANIES

As complex socio-economic systems, companies are not characterized by stability but rather by change and transformation- being subject to the universal law of impermanence according to which everything that is the outcome of a combination of elements must necessarily dissolve when different causes from those leading to the emergence of the combination occur. Consequently, in their quality as nonmechanical socio-economic systems they are born, live, grow and die, going equally through evolutions and involutions that are closely linked to some forces that interact and condition each other.asset liquidation, dissolving companies, accounting
