Which outcome results when exceeding the Curie temperature in gadolinium?

A)Loss of spontaneous magnetization occurs
B)Enhanced piezoelectric effect amplifies vibration
C)Increased thermoelectric efficiency emerges
D)Increased superconductivity onset temperature arises

💡 Explanation

Above the Curie temperature, thermal energy disrupts spin alignment; therefore, spontaneous magnetization is lost because the exchange interaction maintaining alignment weakens significantly, rather than enhancing other phenomena under entirely different physical mechanisms.
