Superconductivity in the splat-cooled UMo alloys

Popis výsledku v původním jazyce

We have investigated the superconductivity in splat-cooled UMo alloys by low-temperature resistivity and specific-heat measurements down to 0.4 K. The ?-U materials, such as U-Mo15 (with 15 at.% Mo doping), exhibit a conventional BCS superconductivity with Tc = 2.1 K and upper critical field exceeding 5 T, much higher than that for ?-U materials. The alloys with <10 at.% Mo doping consist of a mixed ? + ?-U phase. The superconducting transition in the U-Mo6 revealed by a smooth decrease below 1.5 K anda sharp drop at 0.6 K in the resistivity indicating that ?-U grains are embedded in the ?-U matrix. The superconductivity transition was revealed by ?-type peak at Tc in the C(T) curve only for U-Mo15, while only one broad peak at Tc in the C(T) curves were observed for other UMo splats. With applying the magnetic fields, the resistivity jumps and specific-heat peaks move to lower temperatures. (C) 2015 Vietnam Academy of Science & Technology.
