Thickness-dependent magnetic properties of oxygen-deficient EuO
M. Barbagallo, T. Stollenwerk, J. Kroha +12
We have studied how the magnetic properties of oxygen-deficient EuO sputtered thin films vary as a function of thickness. The magnetic moment, measured by polarized neutron reflect…

Efficient construction of maximally localized photonic Wannier functions: locality criterion and initial conditions
Tobias Stollenwerk, Dmitry N. Chigrin, Johann Kroha
Wannier function expansions are well suited for the description of photonic- crystal-based defect structures, but constructing maximally localized Wannier functions by optimizing t…
