Abstract
The possibility of the existence of ferromagnetic order in Ru monolayers on the C(0001) graphite surface is studied using electron induced spin-polarized secondary electron emission (SPSEE). Below a surface Curie temperature of approximately 250K we find ferromagnetic order of the Ru monolayer. The growth mode of Ru on C(0001) is investigated by Auger electron spectroscopy (AES). We find, that the initial growth occurs laterally until a homogenous monolayer is formed. Our study provides the first observation of spontaneous, two-dimensional ferromagnetic order of a 4d transition element.
To investigate the spin-polarization and domain pattern in ultrathin films and multilayers, we develop a novel technique: scanning ion microscopy with polarization analysis (SIMPA). A highly focused Ga
