Electronic correlations in short period (CrAs)${}_n$/(GaAs)${}_n$ ferromagnetic heterostructures

L. Chioncel, I. Leonov, H. Allmaier +4

We investigate half-metallicity in [001] stacked (CrAs)${}_n$/(GaAs)${}_n$ heterostructures with $n\le 3$ by means of a combined many-body and electronic structure calculation. Inter…
