摘要: In this work we explore by means of spin-polarized scanning tunneling microcopy/spectroscopy (SP-STM/STS) and ab initio calculations the magnetic electronic properties thin MnAu alloyed films. The films are produced deposition small amounts Au at RT on a Mn(001) surface. On microscopy images surface AuMn alloy presents $c(2\ifmmode\times\else\texttimes\fi{}2)$ reconstruction. From SP-STM/STS measurements find out that layers coupled antiferromagnetically with above below. Comparing result from found origin contrast is due to peak $0.15\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$ Fermi level spatially placed Mn sites. also moments atoms higher in than pure
