Effect of Element Doping and Substitution on the Electronic Structure and Macroscopic Magnetic Properties of SmFe-based Compounds
Takuya Yoshioka, Hiroki Tsuchiura, Pavel Novák
The mechanisms underlying the enhancement of magnetic anisotropies (MAs) of Sm ions, owing to valence electrons at the Sm site and the screened nuclear charges of ligands, are clar…
Finite-temperature magnetic properties of Sm2Fe17Nx using an ab-initio effective spin model
Shogo Yamashita, Daiki Suzuki, Takuya Yoshioka +2
In this study, we investigate the finite-temperature magnetic properties of Sm2Fe17Nx (x = 0,3) using an effective spin model constructed based on the information obtained by first…
Statistical and Analytical Approaches to Finite Temperature Magnetic Properties of SmFe
Takuya Yoshioka, Hiroki Tsuchiura, Pavel Novák
To investigate the magnetic properties of SmFe, we construct an effective spin model, where magnetic moments, crystal field (CF) parameters, and exchange fields at 0 K are d…
The spin-state crossover and low-temperature magnetic state in yttrium doped PrCaCoO
K. Knizek, J. Hejtmanek, M. Marysko +6
The structural and magnetic properties of two mixed-valence cobaltites with formal population of 0.30 Co ions per f.u., (PrY)CaCoO ( a…
Non-collinear magnetic structures of TbCoO and DyCoO
K. Knížek, Z. Jirák, P. Novák +1
The orthoperovskites TbCoO and DyCoO with Co in a non-magnetic low-spin state have been investigated by neutron diffraction down to 0.25 K. Magnetic ordering is evid…
Spin state transition and covalent bonding in LaCoO3
V. Křápek, P. Novák, J. Kuneš +3
We use the dynamical mean-field theory to study a p-d Hubbard Hamiltonian for LaCoO3 derived from ab initio calculations in local density approximation (LDA+DMFT scheme). We addres…
Sum-rules for electron energy-loss near-edge spectra
Ján Rusz, Olle Eriksson, Pavel Novák +1
We derive four sum-rule expressions for spectra measured in electron energy-loss near edge structure experiments. These sum-rules permit the determination spin and orbital magnetic…
