Temperature hysteresis of the magnetization in orthoferrites at the compensation point
Derkachenko V.N., Kadomtseva A.M., Timofeeva V.A., Khokhlov V.A.
A first-order transition was observed in orthoferrites, for the first time, in a field near the compensation point. The value of the exchange field from the discontinuities of the magnetization on the phase boundaries with 0=0 and θ=π. A thermodynamic explanation of this phenomenon is offered.
