For 10 points, name this type of magnetism exhibited at temperatures below the Curie point by cobalt, nickel, and iron.
This property is acquired not continuously, but in small discrete steps, as demonstrated by Barkhausen noise. It can be explained by the Ising model, and is exhibited by manganese-containing Heusler alloys. Materials with this property display coercivity and remanence, which are related to the size and shape of the S-shaped curves obtained by plotting H against M, the hysteresis loop. It is history-dependent and arises when dipoles align spontaneously, but when these Weiss domains are disrupted it can turn into paramagnetism above a certain temperature.
