The growth and electronic structure of the Cr/InP(100) interface are s
tudied by synchrotron radiation photoemission. At the first stage of g
rowth, Cr atoms cover the whole InP surface. With increasing Cr covera
ge, Cr reacts strongly with the substrate and creates a disruptive int
erface. The electronic structure of the ultrathin Cr film is found to
be different from that of bulk Cr film, and the possibility that magne
tic ordering exists in the ultrathin overlayer of Cr is proposed. (C)
