N2 - Thermodynamic properties of the itinerant-electron metamagnetic (IEM) transition in La(Fe0.88Si0.12)13 compound are discussed. Both the transition field BC and the change in magnetization at the transition ΔM show the thermal variation expected from the theory for the magnetic free energy renormalized by spin fluctuations. The latent heat ΔQ obtained from BC and ΔM agrees with that obtained from heat capacity under magnetic field. Therefore, the thermal variation of ΔQ mainly comes from the magnetic contribution influenced by spin fluctuations.
