Title: Direct Measurement of the Magnetocaloric Effect in La(Fe,Si,Co) 13 Compounds in Pulsed Magnetic Fields

Abstract

We report on magnetization, magnetostriction, and magnetocaloric-effect measurements of polycrystal-line LaFe 11.74Co 0.13Si 1.13 and LaFe 11.21Co 0.65Si 1.11 performed in both pulsed and static magnetic fields. Although the two compounds behave rather differently at low fields (~ 5 T), they show quite similar values of the magnetocaloric effect, namely a temperature increases of about 20 K at high fields (50-60 T). The magnetostriction and magnetization also reach very similar values here. We are able to quantify the magnetoelastic coupling and, based on that, apply the Bean-Rodbell criterion distinguishing first- and second-order transitions.
