The Barkhausen effect concerns tiny inconsistencies in materials displaying this property, which is visualized on a microscopic level by the Ising model. This property lags when the applied field is changed in a process called hysteresis. Disappearing above the Curie temperature, it is seen in materials that remain magnetized after an external magnetic field is removed. For 10 points, name this type of magnetism observed in cobalt, nickname, and, as its name suggests, iron.
