Nabi, Hasan Sadat, Pentcheva, Rossitza
Based on density functional theory (DFT) calculations including an on-site Hubbard $U$ term we investigate the effect of substrate-induced strain on the properties of ferrimagnetic...
First principles study of magnetism in divalent Eu perovskites (2009)
Ranjan, Rajeev, Nabi, Hasan Sadat, Pentcheva, Rossitza
A comparative first principles study has been carried out for EuLiH3 (ELH) and EuTiO3 (ETO) using the generalized gradient approximation +U approach. While ELH exhibits ferromagnetic ground state for...
Interface magnetism in Fe2O3/FeTiO3-heterostructures (2008)
Pentcheva, Rossitza, Nabi, Hasan Sadat
To resolve the microscopic origin of magnetism in the Fe2O3/FeTiO3-system, we have performed density functional theory calculations taking into account on-site Coulomb repulsion. By varying...
