Abstract
We report the result and analysis of the nuclear magnetic resonance (NMR) measurements at the magnetic field of 8.57 T and temperature of 80 K using a single crystal PrNb2Al20. Combining the field angle dependence of NMR spectra, numerical simulation, and band calculation, we deconvoluted the NMR signals from the Nb, Al 48 f, and Al 96g sites. Unfortunately, the overlapping of NMR lines prevents us to extract the NMR signals from the Al 16c site. However, the obtained nuclear quadrupole resonance (NQR) parameters for the Nb and Al 48f sites are consistent with the previous reports [T. Kubo et al., 2014 JPS Conf. Proc. 3 012031; 2015 J. Phys.: Conf. Ser. 592 012093; 2016 J. Phys. Conf.: Ser. 683 012015] and for the Al 96g site are refined to be vQ = 0.98 MHz and η = 0.46.
