摘要: Spontaneous spin-reorientation transitions in ErFeO{sub 3} are studied using ultrasound, magnetic susceptibility, and moment measurements. The properties of the first-order transition happening field sweeps through zero a three-dimensional (H,T) phase diagram material is constructed. Direct measurements allow for precise determination temperature dependence magnetization direction reorientation region. mean-field theory orientation modified to account magnetism erbium subsystem, an excellent agreement with experiment achieved.
