Abstract :
We have investigated, in terms of a micromagnetic model, the influence of the misalignment between local easy axes of exchange coupled grains and that of intergranular phases on the angular dependence of the magnetization reversal processes. It is concluded that the basic characteristics of the phenomenology depend on the occurrence, prior to the global reversal, of magnetization rotation inside the main phase grains
