Superconductivity and itinerant ferromagnetism in d-band metal Y9Co7: A muon spin relaxation study

Abstract: The understanding of the pairing mechanism in unconventional superconductors is a major theoretical challenge. Recent results [PRB 91, 235314 (2015)] designate a local concurrence of itinerant ferromagnetism and bulk superconductivity in Y9Co7 below 2.95 K, as conflicting to a preceding belief that superconductivity occurs in the paramagnetic phase embedded in a principally normal magnetic surroundings. Since the clean-limit condition is satisfied for a pure sample of Y9Co7, the interrogation whether magnetic fluctuations contribute in the formation of Cooper pairs in this sole d-band ferromagnetic superconductor remains open. Since Y9Co7 displays both SC and FM order at ambient conditions, this d-band metal offers a rare opportunity to study the condensation of Cooper pairs in the presence of a molecular field. We want to study this compound by ZF and LF-µSR technique.
