Description
  • The magnetization curves of single-crystal DyFe5Al7 have been measured along the main crystallographic directions in the magnetically ordered state. The temperature dependences of the magnetic moments of the Dy and Fe sublattices and the parameter of the intersublattice exchange have been determined in the model of molecular field. Upon the measurements along the easy axis, jumps of magnetization, the values and critical fields of which strongly depend on temperature, have been revealed near the temperature of magnetic compensation. A model of the magnetization of a ferrimagnet with two magnetic sublattices coupled by weak intersublattice exchange has been suggested. Using this model, analytical expressions for the magnetization curve and critical field of the spin-reorientation transition have been obtained. A magnetic phase diagram has been constructed and magnetic structures that are realized in different fields at different temperatures have been determined. The generalization of the model to the case of a noncollinear Fe sublattice has been generalized.
