    Abstract

    The field dependence of low-temperature thermal conductivity kappa;(H) observed on cuprates is explained by calculating κ(H) microscopically. The heat current carried by low-lying quasiparticles around a vortex core decreases with H due to its depletion by the H-induced moment centered at a core for an underdoped case. This leads to a common and consistent picture on an "anomalous core". κ(H, T) is found to be a useful tool for probing quasiparticle structures in the mixed state in general.
