Single ion anisotropy of Mn doped GaAs measured by EPR
O. M. Fedorych, E. M. Hankiewicz, Z. Wilamowski +1
Electron paramagnetic resonance (EPR) study of MBE grown Mn doped GaAs is presented. The resolved fine structure allows us to evaluate the crystal field parameters of the spin Hami…

Magnetic polarons in weakly doped high-Tc superconductors
E. M. Hankiewicz, R. Buczko, Z. Wilamowski
We consider a spin Hamiltonian describing - exchange interactions between localized spins of a finite antiferromagnet as well as - interactions between a conducting…
