Abstract
Development of spin-polarized scanning tunnel microscopy/spectroscopy (SP-STM/STS) is reviewed and the working principle of SP-STM/STS is discussed with paying special attention to the obtention of the spin-resolved local density of states (LDOS). We discuss the case of bct-Mn epitaxial films grown on Fe(001) whisker. The bct-Mn(001) layers couple antiferromagnetically with the adjacent layers and there is a spin-dependent LDOS peak above the Fermi level, to which highly-polarized two dz2 surface states contribute. The highest lateral magnetic resolution obtained in this system is 0.4 nm. Performing a detailed analysis of the SP-STS measurements, we conclude that the bct-Mn(001) surface has a 60±16% polarization at the energy position of the spin-dependent LDOS peak.
