抄録

We present a comparative study of magnetism in UCoAl and UNi2/3Rh1/3Al single crystals. UCoAl is commonly believed to be an itinerant 5 f-electron metamagnet with Bc < 1 T with uniaxial anisotropy. Pressure and alloying effects on the ground state point to competing ferromagnetic and antiferromagnetic interactions to be responsible for the non-magnetic ground state. UNi2/3Rh1/3Al is a solid solution between an antiferromagnet (UNiAl) and a ferromagnet (URhAl) and may have a similar underlying microscopic mechanism of the non-magnetic ground state. Possible analogies between the two compounds are discussed.
