Gapless Magnetic and Quasiparticle Excitations due to the Coexistence of Antiferromagnetism and Superconductivity in CeRhIn${}_5$ : A study of ${}^{115}$In-NQR under Pressure

S. Kawasaki, T. Mito, Y. Kawasaki +5

We report systematic measurements of ac-susceptibility, nuclear-quadrupole-resonance spectrum, and nuclear-spin-lattice-relaxation time ($T_1$) on the pressure ($P$)- induced heavy…
