Unconventional metamagnetic phase transition in R2In(R=Nd,Pr)with lambda-like specific heat and nonhysteresis
文献摘要：
The phase transition of Nd2In and Pr2In has been studied and found to be between the first-order and second-order nature.Hardly any hysteresis nor obvious cell volume changes are presented.Concurrently the field-triggered metamagnetism is demonstrated with lambda-like peak on specific heat curve.For the field change of 7 T,giant magnetic entropy changes of 13.2 J kg-1 K-1 and 19.5 J kg-1 K-1 and adiabatic temperature changes of 6.5 K and 7.4 K have been achieved in Nd2In and Pr2In alloys respectively,which is partially contributed by strong magnetoelastic coupling represented by high saturation magnetostric-tion of～450 ppm.Such unique feature is proposed to be originated from the delocalized 5d electrons,as evidenced by the negative magnetoresistance caused by the phase transition.
