Abstract
Applying a powder pattern method the magnetic domain structures of polycrystalline intermetallic RMn2Ge2 (where R ≡ La, Ce, Pr, Nd) compounds were studied. The domain structures observed are typical for uniaxial materials. The domain wall energy density γ was determined from analysis of domain structure patterns, using different models of the domain structure. The obtained values are used to determine the intrinsic magnetic material parameters: domain wall width δB, critical diameters of single domain particles Dc and exchange constants A.
