Observation of a pronounced Hebel-Slichter peak in the spin-lattice relaxation rate and implications for gap and pairing symmetry in LaNiGa
P. Sherpa, R. Hingorani, A. Menon +11
We report a pronounced Hebel-Slichter coherence peak in the zero field nuclear quadrupolar resonance (NQR) spin-lattice relaxation rate of the topological crystalline superconducto…
Knight shift measurements probing Fermi surface changes under pressure in CeRhIn
Y. -H. Nian, C. Chaffey, P. Sherpa +5
We report nuclear magnetic resonance (NMR) Knight shift measurements of the In(1) and In(2) sites in CeRhIn as a function of pressure. In contrast to the axis, the in-plane…
Nuclear magnetic resonance studies in a model transverse field Ising system
Y-H. Nian, I. Vinograd, C. Chaffey +6
The suppression of ferroquadrupolar order in TmVO in a magnetic field is well-described by the transverse field Ising model, enabling detailed studies of critical dynamics near…
Measurements of nematic susceptibility with phase sensitive nuclear magnetic resonance in pulsed strain fields
C. Chaffey, C. Williams, M. A. Tanatar +3
We present nuclear magnetic resonance data in BaFeAs in the presence of pulsed strain fields that are interleaved in time with the radiofrequency excitation pulses. In this…
Absence of strong magnetic fluctuations or interactions in the normal state of LaNiGa
P. Sherpa, I. Vinograd, Y. Shi +15
We present nuclear magnetic (NMR) and qudrupole (NQR) resonance and magnetization data in the normal state of the topological crystalline superconductor LaNiGa. We find no evid…
