Which mechanism diminishes magnetic shielding effectiveness in amorphous ferromagnetic alloys?

A)Domain wall pinning
B)Giant magnetoresistance
C)Spin Seebeck effect
D)Anisotropic magnetostriction

💡 Explanation

Domain wall pinning reduces shielding because imperfections hinder domain wall movement; therefore, magnetic flux penetrates more, rather than amorphous alloys exhibiting ideal, easily reversible magnetization because of their disordered structure under stress.
