Abstract
The superconducting transition temperatures of several specimens of reduced SrTiO3 and of Nb-doped SrTiO3 have been investigated as functions of hydrostatic and uniaxial compressive stresses up to 1.8 kbars. Decreases inT c as large as 0.12 K have been observed in specimens under hydrostatic pressure. Because of the lowT c and small compressibility of SrTiO3, Δ(lnT c)/ΔP and Δ(lnT c)/Δ(lnV) are orders of magnitude greater than the corresponding effects in elemental superconductors. The effect of uniaxial stress onT c varied with the direction of stress. Compression along a [111] direction caused large decreases inT c, while both small increases and small decreases inT c have been observed for [100] compression. It is believed that the present results reveal the presence of a sensitive volume dependence in one or more of the parameters important to superconductivity in SrTiO3, and that no significant electron-transfer effects occurred in the range of stresses of this experiment.
