WebFIG. 3: (Color online) (a) Zero-field µSR time spectra collected at 0.3 (green) and 7.0 K (purple) show TRS is preserved in TaRh2B2. (b) Transverse field µSR time spectra for TaRh2B2 collected at 7.0 (top) and 0.3 K (bottom) in an applied field of 30 mT. The solid lines are fits using Eq. 1. The Gaussian decay of the oscillatory signal shows the effect of … WebPart II presents the success stories of finding new superconducting materials. We present several new (non-superconducting) sigma-phases that led to the discovery of three new ternary sigma-phase superconductors. We also present the noncentrosymmetric superconductors TaRh2B2 and NbRh2B2, which have higher than expected upper …

Cava WebMay 4, 2024 · It is a fundamental truth in solid compounds that the physical properties follow the symmetry of the crystal structure. Nowhere is the effect of symmetry more pronounced than in the electronic and magnetic properties of materials-even the projection of the bulk crystal symmetry onto different crystal faces is known to have a substantial impact on the … WebAbstract We report the 11B nuclear magnetic resonance (NMR) measurements on non-centrosymmetric superconductors NbRh2B2 (superconducting transition temperature Tc = 7.8 K) and TaRh2B2 (Tc = 5.9 K) with a chiral crystal structure.
