Effect of the magnetic field on the magnetostructural phase transition in Gd5(SixGe1-x)4

# metadata.dc.description.abstract[].value
The first-order magnetostructural phase transition in Gd5(SixGe12x)4 alloys with x<0.5 and the related
entropy change DS are analyzed from high-field magnetization curves up to 23 T, and differential scanning
calorimetry up to 5 T. The variation of the transition field Ht with the transition temperature Tt is discussed for
fields up to 23 T for the x<0.5 range. From these data, the ratio dHt /dTt , which is related to the strength of
the magnetoelastic coupling, is obtained as a function of x. We show that DS obtained from the ClausiusClapyeron
equation and the Maxwell relation are equivalent for all compositions (0<x<0.5), provided the
Maxwell relation is evaluated only within the transition region. The T and H dependences of DS are accounted
for by modeling the T and H dependences of the magnetization outside the transition.
