Title: Uncovering a Pressure-Tuned Electronic Transition in Bi[subscript 1.98]Sr[subscript 2.06]Y[subscript0.68]Cu[subscript 2]O[subscipt 8+delta] using Raman Scattering and X-Ray Diffraction

Abstract

We report pressure-tuned Raman and x-ray diffraction data of Bi{sub 1.98}Sr{sub 2.06}Y{sub 0.68}Cu{sub 2}O{sub 8+{delta}} revealing a critical pressure at 21 GPa with anomalies in electronic Raman background, electron-phonon coupling {lambda}, spectral weight transfer, density dependent behavior of phonons and magnons, and a compressibility change in the c axis. For the first time in a cuprate, mobile charge carriers, lattice, and magnetism all show anomalies at a distinct critical pressure in the same experimental setting. Furthermore, the spectral changes suggest that the critical pressure at 21 GPa is related to the critical point at optimal doping.
