| Abstract | By using a microstrip ring resonator to measure the temperature dependence of the in-plane magnetic penetration depth k(T) in YBa2Cu3O7� d (YBCO) and Y0.7Ca0.3Ba2Cu3O7� d (Ca-YBCO) epitaxially grown thin films, the linear temperature dependence of the superfluid density qs/m* � 1/k 2 (T) was observed from the under- to the overdoped regime at the temperatures below T T c � 0:3. For the underdoped regime of YBCO and Ca-YBCO thin films, the magnitude of the slope d(1/k 2 (T))/dT is insensitive to doping, and it can be treated in the framework of projected d-density-wave model. Combining these slope values with the thermal conductivity measurements, the Fermi-liquid correction factor a 2 from the Fermi-liquid model, suggested by Wen and Lee, was revealed here with various doping levels. |
