Anomalous dissipation in the mixed state of underdoped cuprates close to the superconductor-insulator boundary

C. Capan, K. Behnia, Z. Z. Li +2

We present a comparative study of Nernst effect and resistivity in underdoped samples of Bi${}_2$Sr${}_2$CuO${}_{6+\delta }$ and La${}_{2-x}$Sr${}_x$CuO${}_4$. The Nernst effect presents a peak in…
