Theoretical analysis reveals discontinuous magnetization changes in heterogeneous alloys, indicating shape anisotropy drives hysteresis in single-domain particles.

Key Points

To elucidate a physical mechanism of magnetic hysteresis in heterogeneous ferromagnetic alloys containing sub-critical single-domain particles.
Modeled magnetization changes governed solely by the rotation of the magnetization vector within single-domain particles lacking domain boundary formation.
Conducted quantitative mathematical derivations for shape anisotropy in particles shaped as ellipsoids of revolution and general ellipsoids.
Demonstrated that continuous variations in applied magnetic fields induce discontinuous shifts in resolved magnetization at critical field thresholds.
Identified particle shape, magnetocrystalline effects, and strain as the primary sources of magnetic anisotropy governing hysteresis behavior.
