| 英文摘要 | A high quality superconducting Li0.68NbO2 polycrystalline sample was prepared by deintercalation of Li ions from Li0.93NbO2. The field-dependent resistivity and specific heat were measured down to 0.5 K. The temperature dependence of the upper critical field is determined. A notable specific-heat jump is observed at the superconducting transition temperature T-c similar to 5.0 K at zero field. Below T-c, the electronic specific heat shows a thermal activated behavior and agrees well with the theoretical result for the BCS s-wave superconductor. It indicates that the superconducting pairing in Li0.68NbO2 has s-wave symmetry. |
