Abstract

The temperature and the magnetic field dependence of the quasiparticle specific heat C_QP(T, H) in La_{2-cursive Greek chi}Sr_{cursive Greek chi}CuO₄ single crystals has been investigated. C_QP(T, H) of overdoped cursive Greek chi = 0.19 crystals obeys the scaling law predicted for "clean" d-wave systems. In contrast, for the under and optimally doped cursive Greek chi = 0.10 and 0.16 crystals. C_QP(T, H) shows the "dirty" d-wave behavior, recently discussed by Kübert and Hirschfeld, indicating a crossover from dirty to clean d-wave behavior with doping.
