← ScienceWhich mechanism limits high-temperature ferromagnetism found in Heusler alloys?
A)Thermal excitation of spin waves✓
B)Increased electron-phonon interactions
C)Suppressed magnetic domain formation
D)Enhanced crystal lattice vibrations
💡 Explanation
Curie temperature limits Heusler alloy ferromagnetism at higher energies because thermal excitation introduces spin waves which misalign magnetic moments; therefore magnetization diminishes rather than alternative effects dominating at these temperatures.
