Abstract
The domain structure of a simple bariumferrite and a sintered Nd-Fe-B magnet was analysed by means of three-dimensional neutron depolarisation between 10 K and room temperature. The temperature dependence of the mean domain size was derived from the measured depolarization matrix both for isotropic and anisotropic specimens.
