| description | This work is devoted to the influence of intergrain exchange interaction on the magnetic hysteresis properties of nanocrystalline composite alloys considering Pr-Fe-B alloy as an example. The appearance of an inflection on the major hysteresis loops of such alloys at lower temperatures is demonstrated and explained. The values of effective coercivity of hard and soft magnetic phases are estimated. It is shown that because of not considering the reduction of the exchange interaction constant on the phase boundary, the Kneller-Hawing’s model does not describe hysteresis magnetic properties of composite exchange-coupled materials well enough. |
