Abstract

Previous heat capacity measurement in zero magnetic field for the low-density second-layer solid ³He adsorbed on graphite showed a peculiar double peak structure. From this measurement a "quantum spin liquid (QSL)" ground state has been suggested. Increasing the magnetic field, theories predict a transition from a QSL phase to a long-range ordered phase called "uuud" at a certain threshold field, which is a measure of the spin gap of the QSL phase. Here we describe an experimental setup for heat capacity measurements of 2D ³He to test the predictions at temperatures below 200 μK in magnetic fields up to 1.2 T.
