Abstract
The intermetallic compound Ni3Al orders in the simple cubic (Cu3Au) crystal structure and becomes ferromagnetic below about 40 K with a spontaneous magnetization extrapolation to absolute zero corresponding to approximately 0.075 μB/Ni atom. An investigation of parts of the Fermi surface has been carried out in stoichiometric single crystals by means of the de Haas‐van Alphen effect in the magnetic field and temperature ranges 20⩽H⩽95 kG and 0.35⩽T⩽8 K, respectively. The results have been interpreted in terms of a band structure model including both the effects of the exchange spin‐splitting of the energy bands and the spin‐orbit interaction. Our combined experimental and theoretical findings will be discussed in relation to current microscopic models of very weak itinerant electron ferromagnetism.This publication has 0 references indexed in Scilit:
