Abstract
Transverse magnetization was measured on a single crystal of an Ising-like antiferromagnet CoCl 2 ·2H 2 O at 1.3 K using the high sensitive pick up coil system under a pulsed magnetic field up to 400 kOe. The antiferromagnetic-paramagnetic transition was observed at 162±5 and 370±15 kOe along the transverse principal x - and y -axes, respectively. These results have been well interpreted with the effective Hamiltonian for the ground Kramers doublet, together with the mixing matrix elements between the ground and excited states. Technical details of the magnetization measurement are also reported.Keywords
