Towards a two-dimensional superconducting state of La${}_{2-x}$Sr${}_x$CuO${}_2$ in a moderate external magnetic field

Abstract

We report a novel aspect of the competition and coexistence between magnetism and superconductivity in the high-$T_c$ cuprate La${}_{2-x}$Sr${}_x$CuO${}_4$ (La214). With a modest magnetic field applied $H\parallel c$-axis, we monitored the infrared signature of pair tunneling between the CuO${}_2$ planes and discovered the complete suppression of interlayer coupling in a series of underdoped La214 single crystals. We find that the in-plane superconducting properties remain intact, in spite of enhanced magnetism in the planes.
