Effect of uniaxial strain on the metal-insulator transition in Ti-substituted Ca3Ru2O7

ORAL

Abstract

We present results of electrical transport studies on the metal-insulator transition (MIT) in 10% Ti-substituted Ca3Ru2O7 under uniaxial strain. We observe a large (~10K) modulation of the Mott transition temperature under application of high (<1%) ab-plane uniaxial strain. For low strains we find an anomaly across T_{MIT} in the linear response elastoresistive susceptibility. Complementary scanning near-field optical microscopy measurements have been performed on the same samples.
