It is shown that the de Haas–van Alphen (dHvA) effect in ferromagnetic metals can give information about the Stoner T2 term in the temperature dependence of the magnetization, without interference from spin wave contributions. In particular, the temperature dependence of the dHvA frequency for a very weak itinerant electron ferromagnet could distinguish clearly between conflicting theories of these materials.

High field magnetization and susceptibility of Co-based compounds Y(Co1−xA1x)2 are investigated in the paramagnetic region 0≤x≤0.11. In all the region, a sharp metamagnetic transition is observed, while the susceptibility shows a maximum at finite temperature Tmax. The transition field Hc exhibits a positive shift proportional to T2 with temperature. The Hc in the ground state is found to be proportional to Tmax. The experimental results are discussed with a new theory for itinerant electron metamagnetism based on the spin fluctuation model.
