Investigation of the growth and magnetic properties of highly oriented films of the Heusler alloy Co2MnSi on GaAs(001)

L. J. Singh, Z. H. Barber, A. Kohn +4

Highly (001) oriented thin films of Co2MnSi have been grown on lattice matched GaAs(001) without a buffer layer. Stoichiometric films exhibited a saturation magnetization slightly…
