This paper describes neutron scattering experiments on a spin glass, C
u-Mn, an inhomogeneous antiferromagnetic alloy, gamma-Mn-Ni, and the c
rystal field excitations in PrAl3. In all materials the magnetic part
of the scattering has been isolated using polarisation analysis with t
he long wavelength polarised neutron diffractometer-spectrometer (LONG
POL) installed at the HIFAR reactor at Lucas Heights.
