Magnetic-Field Induced Localization in the Normal State of Superconducting La_2-xSr_xCuo_4

A. Malinowski, Marta Z. Cieplak, A. S. van Steenbergen +5

Magnetoresistance measurements of highly underdoped superconducting La_{2-x}Sr_xCuO_4 films with $x=0.051$ and $x=0.048$, performed in dc magnetic fields up to 20 T and at temp…
