Ferromagnetism in 5f-band metamagnet UCoAl induced by Os doping
Original language description
UCoAl is a 5f-band metamagnet with a uniquely low transition field, 0.7 T, extremely sensitive to any perturbation such as elemental substitution. We study variations of magnetic properties in the UCoAl-UOsAl system on single and polycrystalline samples with different Os concentration. Os can substitute Co in UCoAl up to 20%, while preserving the ZrNiAl structure type. Pure UOsAl is hexagonal Laves phase. It is a weak Pauli paramagnet. Even a 2%-substitution of Os for Co shifts the critical field to zero and stabilizes ferromagnetism with the Curie temperature 26 K and uranium magnetic moment 0.4 mB. Higher Os content enhances both characteristics. All magnetic response is concentrated into the c-axis; the susceptibility for magnetic field along basal plane is low and practically temperature-independent. This work completes the study of the alloying of UCoAl with late transition metals and indicates that the non-magnetic band metamagnetism is very limited in the concentration range.
