The two-dimensional interacting electron gas at Landau level filling factor \ensuremathν\phantom\rule0ex0ex=\phantom\rule0ex0ex1 and temperature T\phantom\rule0ex0ex=\phantom\rule0ex0ex0 is a strong ferromagnet; all spins are completely aligned by arbitrarily weak Zeeman coupling. We report on its thermodynamic properties using a many-body perturbation theory approach and concentrating on the recently measured temperature dependence of the spin magnetization. We discuss the interplay of collective and single-particle aspects of the physics and the opportunities for progress in our understanding of itinerant electron ferromagnetism presented by quantum Hall ferromagnets.
