Which outcome occurs when exceeding the Curie temperature limit of a ferromagnetic write head material?

A)Irreversible demagnetization occurs
B)Magnetostriction increases linearity
C)Hysteresis loop area expands
D)Increased domain wall mobility

💡 Explanation

Irreversible demagnetization is a consequence of exceeding the Curie temperature in a ferromagnetic material because thermal energy overcomes exchange interactions, resulting in the loss of spontaneous magnetization. Therefore, the head demagnetizes, rather than merely changing magnetostriction under lower driving currents.
