Materials exhibiting the "anti" version of this can interact with materials exhibiting this property via exchange bias.
Materials exhibiting the "anti" version of this can interact with materials exhibiting this property via exchange bias. This property occurs in regions that are separated by Bloch and Neel walls, and when this property waxes or wanes, those domains change sizes and cause popping noises known as the Barkhausen effect. The lag in this property is known as hysteresis, and this property occurs below the Curie temperature. For 10 points, name this phenomenon exhibited by nickel, cobalt, and its namesake material, iron.
