Abstract
The changes in domain structures of h.c.p. cobalt single crystals of (112̄0) and (101̄0) orientations with temperature in the range 20–380°C have been studied dynamically in a 1000 kV electron microscope and recorded on the VTR. The results show unambiguously that the easy direction of magnetization in the domain rotates from the c-axis to a direction in the c-plane and vice versa with increasing and decreasing temperature in the range 200–330°C. The temperature dependence of the angle of rotation from the c-axis measured on the images agrees well with that calculated from the known anisotropy data.Keywords
