Virtual Laboratory : High Pressure

This is a special High Pressure Cell made from non-magnetic materials at the High Pressure Laboratory, Troitsk, Moscow. It has electrical connections and optical fibre inputs which allow us to make electrical transport and optical measurements at pressures up to 25,000 Atmospheres at temperatures down to 300mK in magnetic fields up to 21.5T.

It is currently being used to study the two dimensional electron system in GaAs/GaAlAs heterojunctions where the high pressure allows the Zeeman splitting (electron g-factor) to be tuned through zero in order to generate new spin textured states of matter.
