Free radicals and liquid oxygen demonstrate this property because it is the result of the spins of unpaired electrons.
In photochemical reactions, triplet transition states but not singlets have this property, and Neel relaxation is observed in particles exhibiting the "super-" form of it. A Brillouin (BREEL-won) curve plots changes in this property against the ratio of auxiliary field strength to temperature, and the behavior of materials with this property is approximated by Curie's law. These objects do not demonstrate hysteresis (his-tur-EE-sis) but do have a permeability stronger than that of free space. Free radicals and liquid oxygen demonstrate this property because it is the result of the spins of unpaired electrons. Name this property of substances which only become magnetized within an applied magnetic field.
