← ScienceWhich outcome weakens a ferromagnet’s alignment when approaching its Curie temperature?
A)Increased electron spin thermal agitation✓
B)Enhanced magnetic domain wall motion
C)Suppressed quantum tunneling coherence
D)Reduced magnetostrictive stress anisotropy
💡 Explanation
Increased thermal agitation overcomes the exchange interaction, because the mechanism causing ferromagnetic alignment is the exchange interaction, thus the electron spins become randomized. Therefore, the material loses its spontaneous magnetization, rather than a change in domain walls at lower temperatures.
