Abstract

Effect of a magnetic field on ordering of FePd was examined. Single crystals of disordered FePd were heat treated at various temperatures under the magnetic field up to 10T. When the temperature is higher than 793 K, a mono-variant structure of the L10 ordered phase is formed under the magnetic field of appropriate strength. The necessary conditions for the formation of the mono-variant structure are: the ordering proceeds by nucleation and growth process (the temperature of heat treatment must be higher than the spinodal ordering temperature), and magnetocrystalline anisotropy energy is sufficiently large to change the nucleation rates of different variants.
