Pr<sub>4</sub>Ni<sub>3</sub>O<sub>10</sub> Crystals with non-bulk pressure-induced superconductivity

ORAL

Abstract

We present evidence of non-bulk superconductivity under pressure in Pr4Ni3O10 crystals. Resistance measurements revealed field-dependent transitions without true zero resistance, and a maximum onset of ~ 31 K. The transitions were observed using KBr and Nujol pressure media. The charge density wave, which was observed at ambient pressure, was suppressed with pressure. Significant sample-to-sample variation of the superconducting transitions was observed, as well as dependence on the positions of the electrical contacts. Susceptibility measurements indicated a superconducting volume fraction of ~ 10%. Possible origins of the non-percolative superconductivity will be discussed.
