Temperature dependence of the interphase interaction energy of core/shell nanoparticles

Abstract

Within the framework of the Ising model, in the direct exchange interaction approximation by the “average spin” method, the constant of the interphase exchange interaction A(T), which determines the exchange bias field, is estimated. It was shown that A(T) ~ e(−T/T0), where the characteristic temperature T0 is determined by the constant of the exchange interaction between the atoms of the core and the shell.
