Electronic structure of YbFe${}_4$Al${}_8$ antiferromagnet: A combined X-ray photoelectron spectroscopy and first-principles study

Wojciech Marciniak, Grażyna Chełkowska, Anna Bajorek +3

Depending on their chemical composition, Yb compounds often exhibit different valence states. Here we investigate the valence state of YbFe${}_4$Al${}_8$ using X-ray photoelectron spec…
