High-field magnetization of a two dimensional spin frustration system Ni(TeO)X (X = Br and Cl)
J. L. Her, Y. H. Matsuda, K. Suga +4
High-field magnetization, M(), on Ni(TeO)X (X = Br and Cl) were measured by using a pulse magnet. These compounds have a two dimensional crystal structur…
BCS-like Superconductivity in MgCNi3
J. -Y. Lin, P. L. Ho, H. L. Huang +5
The low-temperature specific heat C(T,H) of a new superconductor MgCNi3 has been measured in detail. (C/gammasub_nTc=1.97 is estimated from the anomaly at Tc. At low temperatures,…
Possible evidence for the existence of the Fehrenbacher-Rice band: O K-edge XANES study on Pr1-xCaxBa2Cu3O7
I. P. Hong, J. -Y. Lin, J. M. Chen +4
X-ray absorption near edge structure (XANES), resistivity and thermoelectric power have been measured on Pr1-xCaxBa2Cu3O7. These data reveal an intriguing electronic structure in P…
Order parameter of MgB_2: a fully gapped superconductor
H. D. Yang, J. -Y. Lin, H. H. Li +5
We have measured the low-temperature specific heat C(T) for polycrystalline MgB_2 prepared by high pressure synthesis. C(T) below 10 K vanishes exponentially, which unambiguously i…
Impurity scattering effects on the low-temperature specific heat of d-wave superconductors
C. F. Chang, J. -Y. Lin, H. D. Yang
Very recently impurity scattering effects on quasiparticles in d-wave superconductors have attracted much attention. Especially, the thermodynamic properties in magnetic fields H a…
Depression of quasiparticle density of states at zero energy in La1.9Sr0.1Cu1-xZnxO4
C. F. Chang, J. -Y. Lin, H. D. Yand
We have measured low-temperature specific heat C(T, H) of La1.9Sr0.1Cu1-xZnxO4 (x=0, 0.01, and 0.02) both in zero and applied magnetic fields. A pronounced dip of C/T below 2 K was…
