Abstract
The effect of heat treatment on the structural and magnetic properties of P t3V has been investigated by neutron diffraction and SQUID magnetometry on single crystals. The results indicate that the ordered Cu3Au (L1(2)) struct ure can be stabilised at low temperatures. However, both the atomically ord ered and disordered crystals remain essentially paramagnetic down to at lea st 2 K. Polarised neutron measurements in a field of 4.6 T yielded at 5 K a moment per Pt3V formula unit of 0.009(2) mu(B) for the atomically ordered sample, which was a factor of three larger than that determined for the dis ordered sample but more than two orders of magnitude smaller than that pred icted by band theory.
