Pressure Dependence of de Haas-van Alphen Parameters in Bismuth

The Hall coefficient, A, of a bismuth single crystal has been measured at 4.2^∘{}K, in magnetic fields up to 12 kilogauss, and under liquid helium pressures up to 120 atmospheres. The period (βE₀) of the oscillations in reciprocal field, the phase, and the monotonic part of the magnetic field dependence of A were found to depend on the pressure with small, but nevertheless easily measurable, pressure coefficients. Only the single-period term observable in bismuth when the magnetic field is parallel to the trigonal axis was studied.
