Notes:
Co/CoAl multilayers are grown by molecular beam epitaxy on AlAs/GaAs (001). CoAl is used as a template for the epitaxy of Co. From RHEED and lattice matching considerations bcc Co is expected, but thicker Co layers are probably fcc with stacking faults. The crystallographic structure of the Co layers is unclear at present. Room-temperature magnetization and magnetoresistance data are presented. Co/CoAl multilayers with various CoAl thickness all show in-plane magnetic anisotropies along 〈110〉. Uniaxial anisotropy along 〈110〉 is found to increase with increasing thickness of the CoAl layers in the multilayers. The magnetoresistive effect as a function of the orientation of the current path and the applied field is ascribed to domain-wall effects and internal Lorentz magnetoresistance.
