Possible coexistence of s-wave and unconventional pairing in Na_xCoO_2-yH2O:a new insight from impurity effects
Y. -J. Chen, C. -J. Liu, J. -S. Wang +8
To shed light on the symmetry of the superconducting order parameter in Na_xCoO_2-yH_2O, the Mn doping effects are studied. X-ray absorption spectroscopy verifies that the doped Mn…
Spatially-resolved relaxation dynamics of photoinduced quasiparticles in underdoped YBaCuO
C. W. Luo, P. T. Shih, Y. -J. Chen +6
The spatially-resolved relaxation characteristics of photoinduced quasiparticles (QPs) in CuO planes of underdoped YBCO are disclosed by polarized fs time-resolved spectrosc…
Spatial Symmetry of Superconducting Gap in YBa2Cu3O7-δObtained from Femtosecond Spectroscopy
C. W. Luo, M. H. Chen, S. P. Chen +5
The polarized femtosecond spectroscopies obtained from well characterized (100) and (110) YBa2Cu3O7-δthin films are reported. This bulk-sensitive spectroscopy, combining with the w…
MgCNi3: a conventional and yet puzzling superconductor
J. -Y. Lin, H. D. Yang
The newly discovered superconductivity in MgCNi3, though with Tc<8 K lower than that of the celebrated MgB2, is probably even more interesting in its many puzzling physical propert…
Specific heat of unconventional superconductivity in NaxCoO2-yH2O
H. D. Yang, J. -Y. Lin, C. P. Sun +5
Comprehensive studies of the low-temperature specific heat C(T,H) in NaxCoO2-yH2O are presented. At H=0, a very sharp anomaly was observed at T=4.7 K indicating the existence of bu…
