| 中文摘要 | The transport and superconducting properties of Ho0.75Y0.25Ni2B2C single crystals were investigated to study the competing effects between superconductivity and magnetism. The superconducting transition temperature T-c is 7.6 K, determined from the resistivity transition; meanwhile, the commensurate antiferromagnetic (AFM) transition occurs at T-N of 3.9 K, which is lower than that of pure HoNi2B2C (T-N approximate to 5 K). Ho0.75Y0.25Ni2B2C reentered into the normal state at T-m (T-N < T-m < T-c) when small magnetic fields were applied along the crystallographic c-axis. In contrast to the case in HoNi2B2C, the reentrant behaviour for Ho0.75Y0.25Ni2B2C only appears when the applied field H is along the c-axis, and the reentrant peak position T-P(H) shifts to lower temperature with increasing applied field. We suggest that the disorder of magnetic structure induced by Y doping may account for the significant difference in the reentrant behaviour between Ho0.75Y0.25Ni2B2C and HoNi2B2C. Moreover, there does not exist a deep minimum in the upper critical field H-c2(T) line at T-N of 3.9 K for either H parallel to c or H perpendicular to c. The H-T phase diagram is derived and discussed. |
