摘要: We demonstrate the coexistence of superconductivity and ferromagnetism in Bi${}_{3}$Ni nanostructures that have been prepared by making use novel chemical-reaction paths. characterized their magnetic superconducting properties means magnetometry electrical-transport measurements. Other than bulk geometry, submicrometer-sized particles quasi-one-dimensional nanoscaled strains single-phase undergo ferromagnetic order. Superconductivity confined emerges ferromagnetically ordered phase is stable up to remarkably high fields. Uniquely, hysteresis at zero resistance observed nanostructured Bi${}_{3}$Ni.
