On the Calculation of Effective Anisotropy Constant of Nanoparticle

Abstract:

A correct composition of two kind of magnetic anisotropy of ellipsoidal nanoparticles: crystalline anisotropy and shape anisotropy - has been carried out. It was shown that according to the shape anisotropy the effective anisotropy constant can change non-monotonically. The temperature dependence of effective anisotropy constant on the angle defining the position of effective axis was calculated. It was found out if the angle between the crystalline anisotropy axis and the long axis of nanoparticle exceeds π/4, then the effective constant as well as the position of effective axis has to change non-monotonically according to changing of temperature.
