Oxygen isotope effect on the in-plane penetration depth in underdoped La_{2-x}Sr_{x}CuO_{4} single crystals

J. Hofer, K. Conder, T. Sasagawa +4

We report measurements of the oxygen isotope effect (OIE) on the in-plane penetration depth λ_{ab}(0) in underdoped La_{2-x}Sr_{x}CuO_{4} single crystals. A highly sensitive magnet…
