چکیده انگلیسی
The magnetic properties of trigonal Nd0.9Dy0.1Fe3(BO3)4 substituted compound with the competitive Nd-Fe and Dy-Fe exchange interactions have been investigated. It has been shown that in Nd0.9Dy0.1Fe3(BO3)4 a spontaneous spin-reorientation transition from an ease-axis state to an easy-plane occurs near 8Â K. Anomalies of the magnetization curves are observed in a spin-flop transition induced by the magnetic field Bâc. The calculations were performed using a molecular-field approximation and a crystal-field model for the rare-earth subsystem. Extensive experimental data on the magnetic properties of Nd0.9Dy0.1Fe3(BO3)4 have been interpreted and good agreement between theory and experiment has been achieved using the obtained theoretical dependences.
