Compressibility of BiCu 2 PO 6 : Polymorphism against S = 1 / 2 Magnetic Spin Ladders

Résumé

BiCu 2 PO 6 is an unique example of S=1/2 ladder where the magnetic exchanges are mainly confined in 1D-∞ [BiCu 2 O 2 ] 3+ cationic ribbons, although the existence of shortest Cu-Cu separation between them. Its original magnetic topology gives the most representative example of frustrated quantum ladder to investigate the complex physics behind. Herein, we report the synthesis and characterization of one high-pressure polymorph. In this new phase, the preservation of 1D-∞ [BiCu 2 O 2 ] 3+ units somewhat restacked leads to the preservation of its gapped magnetic ground state and ladder topology. The comparison between both compounds highlight a scare thermodynamic conjuncture, where both the stable ambient pressure (AP) and the metastable high pressure (HP) forms display the same equilibrium volume and superposed volume dependence of the energy , leading to a 1 st order AP  HP transition undetected by DTA.
