← ScienceWhich mechanism limits magnetic domain growth in ferromagnetic materials?
A)Magnetocrystalline anisotropy energy minimization✓
B)Thermally-induced electron orbital suppression
C)Phonon scattering limits electron spin
D)Fermi level shifts decrease magnetism
💡 Explanation
Magnetocrystalline anisotropy dictates domain wall energy is minimized for specific crystal orientations; domain growth stops when forced away from favored axes because further alignment requires more energy, therefore limiting domains rather than alternative constraints that would cause collapse.
