Sažetak
Measurements of surface impedance on optimally doped HgBa2CuO4 single crystal (Tc = 95 K) were performed using a resonant microwave method. By changing the configurations of the microwave electric and magnetic fields we observed various absorption signals - signatures of anisotropic normal state conductivity sigma(ab) and sigma(c). An external DC magnetic field was applied in two orientations: Hdc ||c and Hdc || ab , and the estimate of the upper critical field in them reveals anisotropy of the GL coherence length gamma = 10. Temperature dependence was measured up to 300 K, and a characteristic temperature T* was observed around 180 K indicating a pseudogap opening temperature. Temperature measurements in magnetic field Hdc || c reveal interesting feature of superconducting fluctuations up to 105 K.
