摘要：

Magnetization measurement on Mn(CH3COO)2·4H20 in an external field H0 up to 400 kOe at 1.1 K gives the first clear example of a full magnetization process in a Heisenberg ferrimagnet. Two critical fields Hc1 and Hc2 are found. The system is ferrimagnetic below Hc1, ferromagnetic above Hc2 and a spin canted state appears at Hc1<H0<Hc2. Hc1 and Hc2 are 125 kOe and 288 kOe, respectively for H0//a-axis. The biquadratic exchange interaction is taken into account to explain the magnetization process. © 1979, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
