The transition to this behavior can be shown by a material having a line with a positive y- intercept on an Arrott plot. A particular material class showing this behavior undergoes a martensitic phase transition and is shape-memory alloys. The product of the density of states at the Fermi level with the exchange integral for it must be greater than one according to the Stoner criterion. This property is shown by a gas of lithium atoms cooled to about 150 nanokelvin. It causes jumps in a material's J vs H curve due to alignment within entire domains in the Barkhausen effect. The susceptibility due to this property is equal to a constant over temperature minus theta according to a law partly named for Weiss. For 10 points, name this kind of magnetism that shows permanent magnetism by parallel alignment of domains.
