Abstract Taking profit that the ternary indides Ce2+εPd2-εIn form two branches of solid solutions allowing to access to ferromagnetic (FM, ε > 0) or anti-ferromagnetic (AFM, ε < 0) ground states depending on the relative Ce/Pd concentration 'ε' , we have tested the possibility of a Shastry-Sutherland phase formation by electron doping the trivalent In lattice with tetravalent Sn. Starting from the AFM, ε < 0 side provides the lowest electron concentration conditions increasing the sensitivity to electron doping. For such a purpose low temperature thermal and magnetic properties were investigated on Ce2+εPd2-εIn1-xSnx alloys within the 0 ≤ x ≤ 0.6 range of concentration.

Title Suppression of the Shastry-Sutherland phase driven by electronic concentration reduction in magnetically frustrated Ce2.15Pd1.95(Sn1-yIny)0.9 alloys Type Journal Article

Abstract Exploiting the possibility to switch from antiferromagnetic (AFM) and ferromagnetic (FM) ground states (GSs) in out-stoichiometric branches of

Ce2Pd2In alloys, the stability of Shastry-Sutherland (ShSu) phase of

Ce2Pd2Sn as a function of Sn/In electron doping was studied. Magnetic and specific-heat measurements show that the Ce-rich compositions stabilize the FM-GS throughout the Sn/In-FM substitution, allowing to extend the formation of the ShSu phase up to its collapse in a tricritical point around ycr=0.5. On the other hand, this behavior is quite different from that reported in a recent investigation on the AFM branch where atomic disorder at intermediate Sn/In-AFM concentrations inhibits the formation of the ShSu phase.
