Stability of the 4f-magnetism in Ce2Pd2In under hydrostatic and uniaxial pressure

La2Pd2In: superconductivity and lattice properties at ambient and elevated pressures

“…The unit cell volume V 0 is −1.04% smaller than V (300 K) and the ratio c/a increases by 0.33% upon cooling the sample. There is a striking difference with respect to lattice properties of Ce 2 Pd 2 In (figure 1 in the reference [10]). In the Ce-based compound, the effect on the a-parameter is slightly higher (by Δa/a = −0.75%) and the curvature of its temperature dependence is different (convex or concave for La-and Ce-based system, respectively).…”

“…There were implicit indications of such situation in some cases, based on comparison of hydrostatic and uniaxial pressure effect on magnetism (e.g. for Ce 2 Pd 2 In [10]) and it is important that a case is disclosed now for a system without any f -electrons. However, results of the strain gauge experiment, which has very good precision but depends somewhat on calibration of the gauges, have to be in future compared with high-pressure XRD study, which is superior in absolute accuracy.…”

“…In the frame of our study, we have focused on La 2 Pd 2 In, which is known as a non-magnetic counterpart of the Cebased ferromagnet Ce 2 Pd 2 In [8,9]. An impact of high pressures on the stability of magnetism of Ce 2 Pd 2 In single crystals was explored in [10], making the comparison of lattice properties of the Ce and La isotypes particularly interesting. In addition, the effects of H absorption on crystal lattice and its expansion underlines similarity of both materials [11].…”
