摘要：

The domain size has been determined by means of neutron depolarisation in a series of polycrystalline MnZn ferrites of varying grain size but unaltered composition. For ferrite samples with grain sizes between 0.3 and 3-mu-m, it is found that the domain size is identical to the grain size i.e. no magnetic domain walls are present within the grains.
