It is given by the coupling constant times the number of nearest neighbors divided by Boltzmann's constant, and Onsager's solutions imply that near it the spontaneous magnetization scales as the one-eighth power of the temperature. TRM occurs when a substance is cooled in the presence of a magnetic field below this point, which has an antiferromagnetic counterpart in the Neel temperature. Associated with a second-order critical transition, for ten points, identify this temperature above which a ferromagnetic substance becomes paramagnetic, discovered by the father-in-law of Fr??ic Joliot.
