Tuning the critical magnetic field of the triplon Bose–Einstein condensation in $Ba_{3-x}Sr_xCr_2O_8$


Grundmann, Henrik; Sabitova, Alsu; Schilling, Andreas; Rohr, Fabian von; Förster, Tobias; Peters, Laurens (2016). Tuning the critical magnetic field of the triplon Bose–Einstein condensation in $Ba_{3-x}Sr_xCr_2O_8$. New Journal of Physics, 18(3):033001.

Abstract

The structure and magnetic interactions of the triplon Bose-Einstein condensation candidates $Ba_3Cr_2O_8$ and $Sr_3Cr_2O_8$ have been studied thoroughly in the literature, but little is known about a possible triplon condensation in the corresponding solid solution$Ba_{3-x}Sr_xCr_2O_8$. We have prepared various members of this solid solution and systematically examined their magnetic properties in high magnetic fields up to 60 T and at low temperatures down to 340 mK, by means of pulsed field and cantilever magnetometry. From these experiments for x $\in$ {3,2.9,2.8,2.7,2.6,2.5}, we find that the critical fields of $Ba_{3-x}Sr_xCr_2O_8$ decrease monotonically with decreasing Sr content x. This change is in good agreement with the earlier reported variation of the magnetic interactions in these compounds.
