Controlling the magnetocrystalline anisotropy of ε-Fe2O3

Autor: Imran Ahamed, Ralph Skomski, Arti Kashyap

Publikováno v: AIP Advances, Vol 9, Iss 3, Pp 035231-035231-4 (2019)

The magnetocrystalline anisotropy of pristine and Co-substituted ε-Fe2O3 is investigated by density functional calculations. The epsilon-iron oxide is the only polymorph of Fe2O3 magnetoelectric in its antiferromagnetic ground states other crystalli

Magnetocrystalline anisotropy of ε-Fe2O3

Autor: Imran Ahamed, Rohit Pathak, Ralph Skomski, Arti Kashyap

Publikováno v: AIP Advances, Vol 8, Iss 5, Pp 055815-055815-5 (2018)

The epsilon Fe2O3 phase of iron oxide has been studied to understand the spin structure and the magnetocrystalline anisotropy in the bulk and in thin films of ε-Fe2O3 and Co-doped ε-Fe2O3. The preferential magnetization direction in the nanoparticl

Half-metallic magnetism in Ti3Co5-xFexB2

Autor: Rohit Pathak, Imran Ahamed, W. Y. Zhang, Shah Vallopilly, D. J. Sellmyer, Ralph Skomski, Arti Kashyap

Publikováno v: AIP Advances, Vol 7, Iss 5, Pp 055713-055713-6 (2017)

Bulk alloys and thin films of Fe-substituted Ti3Co5B2 have been investigated by first-principle density-functional calculations. The series, which is of interest in the context of alnico magnetism and spin electronics, has been experimentally realize
