Antiferromagnetci Coupling of a Cr Overlayer to Fe(100)

F. U. Hillebrecht, Ch. Roth, R. Jungblut, E. Kisker and A> Bringer

The magnetic moment of Cr overlayers deposited on Fe(100) was investigated 
by spin-resolved core level photoemission. data for the Cr 3p level show 
that a monolayer of Cr is ferromagnetically ordered with a magnetic moment 
oriented antiparallel to the Fe moments. The results suggest that at room 
temperature the moment of a Cr monolayer on Fe is of the order of 0.5 to 1
