Magnetic dichroism effect of binary alloys using circularly-polarized x-ray

PDF Version Also Available for Download.

Description

We have studies the magnetic propertied of CoNi binary alloy films with various atomic compositions using soft x-ray magnetic circular dichroism (XMCD) technique. The alloy films were deposited on single Cu(100) crystals in situ using our well-established epitaxial growth technique to achieve a layer-by-layer growth and a metastable fcc structure, with all films exhibiting an in-plane magnetic anistrophy. Utilizing the element-specific ability and nanostructure magnetization sensitivity of this technique, we have been able to perform the absorption measurements at L2 and L3 edge of Co and Ni atoms and observed large dichroism signals. The extraction of spin moment and orbital ... continued below

The extraction of spin moment and orbital moment for varying elemental stoichiometry using magneto- optical sum rules is discussed.
