The relationship of the micromagnetic structure, the contributions of various crystalline phases and hysterons obtained by the first order reversal curves (FORC) method in sintered (NdDy)(FeCo)B magnets is discussed. The distribution map of parameters of magnetic hysteresis partial loops that allows the separation of various spin ensembles to the magnetization has been built.



This work was carried out in the framework of re-alization of the complex research direction 11.1 of VIAM “Thermal stable hard magnetic materials and mathematical models of calculation of their temperature characteristics for new generation navigation devices.” (“Strategic directions of the development of materials and technologies of their processing for the period up to 2030.”)
