Magnetocaloric effect of LaFe11.35Co0.6Si1.05 alloy
文献摘要：
The aim of the present paper was to study the large magnetocaloric effect observed in LaFe11.35-Co0.6Si1.05 alloy.X-ray diffraction(XRD)result reveals a coexistence of two crystalline phases:a dominant La(Fe,Si)13-type and a minor α-Fe(Co,Si).It is confirmed by the M?ssbauer spectroscopy and microstructural observations accompanied by an energy-dispersive spec-troscopy(EDS)analysis.The value of the magnetic entropy changes(|SM|)in the vicinity of the Curie tem-perature(Tc=268 K)was calculated using thermomag-netic Maxwell relation,and it equals to 21.4 J·kg-1·K-1 under the change in an external magnetic field ofμ0ΔH=3T.The investigation of magnetic phase transi-tion was carried out using the Landau theory,an analysis of the field dependences of the magnetic entropy change and universal scaling curve,revealing the second order of phase transition in the studied material.
