Abstract
Magnetic properties of NpOs2,NpAl2. NpCo2Si2, NpAs, and NpSn3 are investigated by high pressure Mössbauer spectroscopy using the 60 keV transition in237Np. A wide spectrum between itinerant (band-like) electron behaviour and highly localized 5f electron magnetism is observed. Delocalization of 5f electrons may be determined by direct 5f-5f overlap between neighbouring Np ions or may be mediated by the valence electrons of the alloying partner.
