Effects of superconducting gap anisotropy on the flux flow resistivity in Y(Ni_{1-x}Pt_x)_2B_2C
K. Takaki, A. Koizumi, T. Hanaguri +7
The microwave complex surface impedance Z_s of Y(Ni_{1-x}Pt_x)_2B_2C was measured at 0.5 K under magnetic fields H up to 7T. In nominally pure YNi_2B_2C, which is a strongly anisot…
The electronic state of vortices in YBa2Cu3Oy investigated by complex surface impedance measurement
Yoshishige Tsuchiya, Katsuya Iwaya, Kentarou Kinoshita +6
The electromagnetic response to microwaves in the mixed state of YBa2Cu3Oy(YBCO) was measured in order to investigate the electronic state inside and outside the vortex core. The m…
Dynamics vs electronic states of vortex core of high-T_c superconductors investigated by high-frequency impedance measurement
A. Maeda, Y. Tsuchiya, K. Iwaya +9
Dynamics of vortices reflects the electronic states of quasiparticles in the core. To understand this, we investigated the following three issues. (1) We investigated the complex s…
Reduction of the Superfluid Density in the Vortex-Liquid Phase of Bi2Sr2CaCu2Oy
Tetsuo Hanaguri, Takashi Tsuboi, Yoshishige Tsuchiya +2
In-plane complex surface impedance of a Bi2Sr2CaCu2Oy single crystal was measured in the mixed state at 40.8 GHz.The surface reactance, which is proportional to the real part of th…
