| Samenvatting | UNiGe adopts the orthorhombic TiNiSi-type of structure and exhibits in zero field two different antiferromagnetic
structures. Both are noncollinear with significant a axis component. Magnetic measurements indicate
two metamagnetic-like transitions with the field applied along the b or the c axis. Neutron diffraction studies
in magnetic fields applied along the c axis reveal above the second metamagnetic-like transition a canted
ferromagnetic structure. U magnetic moments of 1.1660.04 mB exhibit a ferromagnetic c axis component of
1.0460.04 mB and an antiferromagnetic a axis component of 0.5260.05 mB . Observation of such a canted
ferromagnetic structure in UNiGe provides strong evidence for presence of anisotropic exchange interactions.
The fact that the a axis component cannot be well aligned above the second metamagneticlike transition
indicates that the antiferromagnetic interaction between the a axis components is much stronger than between
the others. |
