Abstract :
Spin-polarized scanning tunneling microscopy and spectroscopy (SP-STM/STS) opens up new real atomic scale magnetism. Interlayer exchange coupling of ultrathin Fe(001) films grown on the antiferromagnetically stacked bct-Mn(001) layers have been studied. The ordered c(2x2)-MnAu(001) surface alloy films were studied and found a high magnetic moment for Mn spins (>4 Bohr magneton), an antiferromagnetic coupling between layers, and a ferromagnetic coupling in the same layer.
