WebThe nuclear spin-lattice relaxation rate 1/T1 shows no coherence peak below Tc, which suggests the unconventional nature of the superconductivity. In the normal state, 1/T1T increases with decreasing temperature T at low temperatures below T=200 K for TaRh2B2 and T=15 K for NbRh2B2, while the Knight shift remains constant. WebWe report the observation of multigap superconductivity in TaRh2B2. We show TaRh2 B2 is a bulk type-II superconductor with a transition temperature Tc = 6.00(5) K. We present transverse-field muon spin relaxation data where the superconducting gap can be fit using a two-gap (s + s)-wave model.We also report the zero-field electronic specific heat in the …
