Abstract

UFe10Si2 single crystals with ThMn12-type structure were studied by X-ray diffraction and magnetisation measurements. A uniaxial anisotropy, a saturation magnetisation of 19.5 mu(B) f.u.(-1) and a type-1 first order magnetisation process, for fields applied along the hard a axis, were observed in agreement with previous powder results. The anisotropy constants K-1, K-2 and K-3 were obtained from the magnetisation curves along the hard axis. The analysis of the first order magnetisation process, through the simultaneous measurement of the longitudinal (parallel to H) and transverse (perpendicular to H) components of the magnetisation, assigned it to a rotation of the total magnetisation. The results indicate an important contribution of the uranium sublattice to the magnetism in this compound.
