Kinetics of magnetization processes in a quasi-one-dimensional Ising superantiferromagnet [{CH3}3NH]CoCl3 · 2H2O

The processes of magnetization reversal in a single crystal of CoTAC are investigated in the temperature range 4.2–0.5 K. The relaxation processes as a function of the magnetic field, temperature, and time are studied. It is shown that the results obtained are described within the model of interacting superparamagnetic formations—nanoclusters. The characteristic constants of interaction, the energy of barriers and the size of domains are determined.
