← ScienceWhich risk increases significantly when ferromagnetic nanoparticles exceed their Curie temperature?
A)Loss of magnetic hyperthermia benefits✓
B)Enhanced quantum tunneling phenomena
C)Increased mechanical wear propagation
D)Faster catalytic oxidation reaction rates
💡 Explanation
A loss of therapeutic effect occurs because exceeding the Curie temperature inhibits magnetic domain alignment (Curie Point transition); therefore, magnetic hyperthermia treatment is ineffective, rather than enhanced particle properties in an applied field.
