Interplay between crystal structure and magnetism in CeCrB
Mirosław Werwiński, Andrzej Szajek, Andrzej Kowalczyk
CeCrB belongs to the family of MTB ternary metal borides, some of whose magnetic phases have recently been identified as quantum spin dimers. Employing density functional t…
Electronic structure of UGe at ambient pressure: comparison with X-ray photoemission spectra
M. Samsel-Czekała, M. Werwiński, A. Szajek +2
Based on experimental crystallographic data, electronic structure of UGe have been calculated and compared with our results of X-ray photoelectron spectroscopy (XPS) measuremen…
X-ray photoemission spectrum, electronic structure, and magnetism of UCuSi
J. A. Morkowski, G. Chełkowska, M. Werwiński +3
The room temperature X-ray photoemission spectrum of the ferromagnetic compound UCuSi (T = 100 K) was measured using an Al K source. Related theoretical spectra wer…
Induced magnetic ordering in alloyed compounds based on Pauli paramagnet YCo
