Abstract

The magnetocrystalline anisotropy of uniaxial (PrDy)(FeCo)B rare-earth magnets is determined using the Akulov model and studied in the 2–300 K temperature. The (PrDy)(FeCo)B samples demonstrate the power dependence of anisotropy constant K(T) on saturation magnetization MS(T) in the temperature range 2–300 K with exponents m = 1.7–2.1, according to the empiric Callen–Callen rule. A deviation of power dependence K(\(M_{S}^{m}\)) is observed in the samples with the Gd impurity. Possible causes of the deviation from the Callen–Callen rule and variations of exponent m are discussed.
