Abstract
The domain structures in ordered regions of equiatomic platinum-cobalt are found to be typical of materials with high uniaxial anisotropy and low saturation magnetization. The distribution of the easy axes of discrete ordered regions within each grain confirms previous work on the nature of the ordering. The width of the domains is approximately accounted for in terms of the known properties of the material, and their behaviour in applied fields shown to resemble that of other uniaxial materials.
