TRANSPORT AND MAGNETIC-PROPERTIES OF CO35PD65 FILMS

Co35Pd65 films were made by the vapor-deposition method at temperature T-S = 180 degrees C and in a vacuum about 10(-6) Torr. Thickness of t he films varies from t = 87 to 2500 Angstrom. We have measured the mag netotransport properties, which include the room-temperature resistivi ties, with fields parallel, transverse (or perpendicular), and normal to the direction of the probe current (rho(parallel to), rho(perpendic ular to), and rho(N)), respectively. With regard to the magnetic prope rties, we used the SQUID and MOKE magnetometers to obtain the hard-axi s and/or easy axis hysteresis loop. Both transport and magnetic data s how that as t is smaller, there is a changeover from the out-of-plane to the in-plane anisotropy, and the transition region can be distinctl y determined at t = t(C) congruent to 500 Angstrom. We also studied th e t dependence of the saturation field H-S in three directions. Other experiments performed on these films include the Hall effect, the Auge r depth profile, and the X-ray diffraction measurements. All the data are summarized together for a complete discussion on the physical char acteristics of the Co35Pd65 films.
