The exchange bias in MnPd/Co1-xFex bilayers

A systematic study of exchange bias in MnPd/Co and MnPd/Co1-xFex bilayers has been carried out. Very large unidirectional anisotropy constant of 2.2 erg/cm(2) and the appearance of double-shifted loops, ascribed to the coexistence of positive and negative exchange bias, have been observed. The dependence of exchange bias. Unidirectional anisotropy constant and coercivity on thickness, temperature, annealing regime and Fe content has been investigated and discussed.

Training and firm performance in economies in transition: a comparison between Vietnam and China

Hình ảnh
This paper provides a comparative analysis on the role of training and its impact on firm performance in some economies in transition in Asia. The starting point is an examination of country contexts and training, and how these have shaped organizational approaches to human resource (HR) training. The paper also reviews the results of recent studies that have investigated the relationship between training and firm performance in Vietnam and China. The review results show that training is positively related to firm performance and reveals some convergence of HR training in both countries. On the basis of this, some caveats on HR training development in the future in these two countries are given. The paper ends with theoretical and practical implications Title:  Training and firm performance in economies in transition: a comparison between Vietnam and China Authors:  Nguyen, Ngoc Thang Quang Truong Buyens, Dirk Keywords:  Economies in transition Firm performance H...

Two-point Green functions of free Dirac fermions in single-layer graphene ribbons with zigzag and armchair edges

Green function technique is a very efficient theoretical tool for the study of dynamical quantum processes in many-body systems. For the study of dynamical quantum processes in graphene ribbons it is necessary to know two-point Green functions of free Dirac fermions in these materials. The purpose of present work is to establish explicit expressions of two-point Green functions of free Dirac fermions in single-layer graphene ribbons with zigzag and armchair edges. By exactly solving the system of Dirac equations with appropriate boundary conditions on the edges of graphene ribbons we derive formulae determining wave functions of free Dirac fermions in above-mentioned materials. Then the quantum fields of free Dirac fermions are introduced, and explicit expressions of two-point Green functions of free Dirac fermions in single-layer graphene ribbons with zigzag and armchair edges are established.
