摘要：
Magnetic property of monatomic Co layers grown on a Pd(0 0 1) surface was surveyed by means of soft X-ray magnetic circular dichroism (XMCD). Hysteresis loops were derived from the magnetic field dependence measurement of the XMCD effect in absorption intensities at the Co L-3 edge. The hysteresis measurements indicate that a bare Co film on Pd(0 0 1) and a sandwich structure of Pd/Co/Pd(0 0 1) show in-plane magnetic anisotropy and out-of-plane magnetic anisotropy, respectively. Temperature dependence of the hysteresis loop reveals that ferromagnetic order with perpendicular magnetic anisotropy in Pd/Co/Pd(0 0 1) is stable even at room temperature. (C) 2010 Elsevier B.V.
