The magnetic property of a thulium-based superconductor, Tm5Rh6Sn18 (superconducting transition temperature Tc = 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 Tc. The internal magnetic field at the muon site, Hμ, 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.
