Title

Unusual Magnetic Phases In Mnco Ultrathin Alloy Films

Abstract

For over a quarter century the Mn:Co magnetic phase diagram has been controversial. We find that for Mn:Co ultrathin alloys with dilute Mn concentration, the Mn and Co moments are coupled parallel for dilute Mn concentrations using X-ray magnetic circular dichroism (XMCD), in contradistinction to the latest accepted bulk results using neutron scattering. To determine if the parallel coupling was the result of epitaxial strain, surface or interface effects, we also performed measurements on very thick films of the same compositions. XMCD shows that thick film Mn:Co alloys have identical magnetic coupling as ultrathin films.
