Abstract :
Co62.5 Ni30Cr7.5 thin films were sputtered onto [100] and [110] Cr single crystals as well as polycrystalline Cr transmission electron microscopy (TEM) foils. Vibrating sample magnetometer (VSM) measurements have revealed the existence of an anisotropy in the in-plane coercivity. This stems from the development of a crystallographic texture in the plane of the film. TEM investigations have found the presence of crystallographic variants in the direction of the HCP c-axis in the CoNiCr films deposited on (100) and (110) Cr surfaces. Lorentz microscopy studies have found specific crystallographic directions. The direction of magnetization within each domain is along the c-axis
