Which outcome destabilizes a ferromagnetic memory cell at elevated temperature?

💡 Explanation

Increased temperature causes increased thermal energy, which can overcome the magnetic anisotropy energy barrier via the Néel-Arrhenius law leading to superparamagnetism, because the magnetic moment fluctuates randomly; therefore the stored data is lost, rather than stabilized by anisotropy.
