Field-Induced Transition in (Nd,Dy)2Fe14B in Ultrahigh Magnetic Fields

We demonstrate the peculiarities of magnetization process in ferrimagnetic intermetallic compound (Nd0.5Dy0.5)2Fe14B, which has been studied theoretically and experimentally using ultrahigh magnetic fields. observe phase transition induced by external fields (up to 170 T) also describe analytically terms critical In this work, first second field-induced transitions, Hc1 Hc2, were estimated, results verified against experimental data for Hc1. Critical field Hc2 predicting place forced-ferromagnetic state was estimated time (Nd0.5Dy0.5)2Fe14B compound. A comparison behavior with basic systems Nd2Fe14B Dy2Fe14B is performed. that, compound, type changed from order due replacement Nd atom Dy one.
