Abstract
Magnetic domain states of completely isolated particles of barium ferr ite between 0.1 and 2 mum in size are investigated by electron hologra phy. Phase distribution is reconstructed digitally by the Fourier tran sform method and converted to interference micrographs. In the interfe rence micrographs single magnetic-domain particles are observed direct ly and clearly for the first time. Furthermore, it is found that singl e-domain and two-domain particles coexist down to sizes as small as ab out 0.1 mum.
