Abstract

This paper describes neutron scattering experiments on a spin glass, Cu–Mn, an inhomogeneous antiferromagnetic alloy, γ-Mn–Ni, and the crystal field excitations in PrAl₃. In all materials the magnetic part of the scattering has been isolated using polarisation analysis with the long wavelength polarised neutron diffractometer–spectrometer (LONGPOL) installed at the HIFAR reactor at Lucas Heights.
