Magnetic-Field-Induced Localization of Quasiparticles in Underdoped La2-xSrxCuO4 Single Crystals
Abstract
Magnetic-field-induced ordering of electrons around vortices is a striking phenomenon recently found in high-Tc cuprates. To identify its consequence in the quasiparticle dynamics, the magnetic-field (H) dependence of the low-temperature thermal conductivity of La2-xSrxCuO4 crystals is studied for a wide doping range. It is found that the behavior of (H) in the sub-Kelvin region changes drastically across optimum doping, and the data for underdoped samples are indicative of unusual magnetic-field-induced localization of quasiparticles; this localization phenomenon is probably responsible for the unusual "insulating normal state" under high magnetic fields.
