Effect of radiation damage on the coexistent antiferromagnetic superconductor SmRh/sub 4/B/sub 4/

Journal Article · · Phys. Rev. B: Condens. Matter; (United States)
; ; ; ;
Radiation-damaged films of coexistent antiferromagnetic superconductor SmRh/sub 4/B/sub 4/ have been studied. The upper critical field, superconducting and magnetic transition temperature, and resistivity ratio were determined as a function of dose. The anomalous dependence of the superconducting transition temperature on resistivity ratio found previously for ''as-made'' films was also found in the damaged films, indicating the anomaly is intrinsic to SmRh/sub 4/B/sub 4/. A disorder-enhanced-spin-flip model is proposed to explain this effect.
