Effects of Pressure on the Superconducting Transition in Tin

Abstract

RECENTLY, Muench1 has investigated the displacement of the critical temperatures T c of tin and indium produced by pressures of up to 100 atmospheres (obtained by compressing helium gas), and by pressure of 1,900 atmospheres (obtained by the ice-expansion bomb technique); and he has measured the value of (ΔH cp)T, where H c denotes the critical magnetic field and p the pressure, at temperatures between 1° K. and T c for each of these metals. These experiment are important in that they provide the most complete data yet obtained on the effects of pressure on the superconducting transition.
