New diamond anvil cell for optical and transport measurements under high magnetic fields up to 60 T

Abstract

We present here a new diamond anvil cell designed to combine high hydrostatic pressure up to 10 GPa, non-destructive, pulsed magnetic fields up to 60 T and low temperature as low as 2 K. Both optical and transport measurements are now achievable. Magneto-photoluminescence set-up under pressure is described in great detail. We report photoluminescence experiments on oriented ruby single crystals exhibiting direct observation of the intrinsic Zeeman splitting of excited states under pressure.
