Effect of Elastic Stress on Some Electronic Properties of Indium

Abstract

We have measured the effect of elastic stress to 0.3 kbar on the resistance at room and helium temperatures and on the superconducting transition temperature of In whiskers. These whiskers have diameters of about 1 v and axes parallel to a closest-packed or <101> direction. dT c /da is 51±7 mK/kbar, in disagreement with results obtained by measuring the change in length of In crystals as they pass through the superconducting transition. At room temperature, Ap/pa=a- {-b(r ) where a= (-0.4±0.2)X10~5 bars" 1 and b= (14±2)X10-9 bar" 2 .

“…As an example, unconventional superconductivity often emerges around the point where antiferromagnetic order is suppressed by hydrostatic pressure [1]. Strain has been occasionally used as a tuning parameter [2][3][4][5][6], but is less widely employed than pressure. Recently, new piezo-based strain-tuning devices have been presented [7,8] and used in the study of ruthenates [9,10] and SmB 6 [11].…”
