The process of paramagnetic saturation in real substances is considered by means of the molecular field method and by Smart's elaboration of the Oguchi method. The magnetic moment and short-range order parameters are calculated as a function of the external field. Some qualitative rules are obtained which describe general tendencies toward saturation. The possibility arises that paramagnetic materials in high fields may change into a state of greater stability by altering their exchange couplings.

Pairwise effective potentials in first seventeen shells of the Ni-22.5at.%Fe alloy are calculated using model potential method with account of the linear size effect. Using obtained values of pairwise effective potentials, the short range order parameters on the first seventeen shells of alloy are calculated by Krivoglaz-Clapp-Moss method. The calculated values ​​of the short-range order parameters were fitted to the experimental values ​​by varying the parameters of static atomic displacements. Reliable value of critical temperature of order-disorder phase transition in Ni-22.5at.%Fe alloy was calculated using obtained meanings of pairwise effective potentials.

X Ray Scattering

Diffuse X-ray scattering intensity was measured in polycrystalline samples of Ni–Nb system. From this diffuse scattering intensity, short-range order parameters and size effect parameters were calculated. The absolute value of short-range order parameters suggest a local order present in this alloy. The ordering potential was calculated on the basis of the statistical pseudopotential theory of ordering and it was found that the calculations take into account the experimentally observed sign of the short-range order parameters.
