Abstract

The magnetic property of a thulium-based superconductor, Tm₅Rh₆Sn₁₈ (superconducting transition temperature T_c = 2.2 K), is investigated by muon spin relaxation (μ SR). Below around 6 K, the development of a quasi-static local magnetic field is clearly inferred from the observation of spontaneous oscillation signal in the μ SR spectra under zero external field, where the magnetism persists even below T_c. The internal magnetic field at the muon site, H_μ, is estimated to be approximately 175 Oe. The fractional volume of the magnetic component is estimated to be 100%, strongly suggesting that the magnetism coexists with superconductivity.
