Reentrant quantum criticality in Yb2Pd2Sn

The Magnetic Field Induced Ferromagnetism in EuPd2Sn4 Novel Compound

“…[6] In the past, we conducted a systematic investigation on RÀPdÀX (R ¼ Eu, Yb, Ce; X ¼ In, Sn) ternary compounds, among which a certain number of them exhibited anomalous physical behavior. [7][8][9][10] Concerning the EuÀPdÀSn system, novel compounds have been discovered, such as Eu 3 Pd 2 Sn 2 and EuPdSn 2 , showing a stable Eu 2þ magnetic state and complex magnetic structures. [11][12][13] This last feature, together with magnetic anisotropy, seems to characterize many compounds belonging to EuÀTÀX systems (T ¼ transition metals; X ¼ p-block elements).…”

“…In the last years we have carried out a systematic investigation on R-Pd-X ( R = Eu, Yb, Ce; X = In, Sn) ternary compounds among which a certain number of them exhibited anomalous physical behaviour [2,3,4,5].…”

Pressure-induced antiferromagnetic dome in the heavy-fermion Yb2Pd2In1−xSnx system

“…In this region of the phase diagram, an increase of pressure induces a growth of resistivity 3,4 , corresponding to a reduced f -c electron coupling and to an increased excitation energy ∆ f . Both of them stabilize the antiferromagnetic phase 6 , clearly suggesting that pressure (either hydrostatic or chemical) shifts a Kondo-lattice system towards the RKKY interaction regime in the Doniach phase diagram 28 .…”

“…[6][7][8][9][10][11][12][13][14] Among them, Yb 2 Pd 2 Sn was recently found to exhibit two pressure-driven quantum critical points (QCPs). 11,15,16 A pressure-induced magnetic instability occurs at 1 GPa (the first QCP), whereas, further pressure increases result in a domelike magnetic phase, which vanishes above 4 GPa (the second QCP). The crystal structure is tetragonal with two types of layers alternatively stacking along the c axis.…”
