Magnetic structure of the heavy fermion compound U(2)Zn(17).
01 January 1986
The phase transition of U(2)Zn(17) at 9.7K has been investigated by neutron powder diffraction. The transition corresponds to the onset of antiferromegnetic order where the U moments are oriented antiparallel to their nearest neighbors within the basal planes and along the c(^) axis of this rhombohedral compound. At 5K, the ordered moments lie within the basal planes and are of magintude 0.8 +- 0.1 mu(beta), which is substantially below the paramagnetic moment of 2.25 mu(beta)/U atom given by high temperature susceptibility data.
