Abstract
Applying a powder pattern method the magnetic domain structures of polycrys talline intermetallic RMn2Ge2 (where R drop La, Ce, Pr, Nd) compounds were studied. The domain structures observed are typical for uniaxial materials. The domain wail energy density gamma was determined from analysis of domai n structure patterns. using different models of the domain structure. The o btained values are used to determine the intrinsic magnetic material parame ters: domain wall width dB, critical diameters of single domain particles D -c and exchange constants A.
