← ScienceWhich outcome destabilizes a ferromagnetic memory cell at elevated temperature?
A)Increased probability of superparamagnetism✓
B)Decreased magnetic hysteresis coercivity
C)Enhanced spin-orbit coupling effects
D)Increased magnetic domain wall pinning
💡 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.
