We have used pulsed 63,65Cu nuclear quadrupole resonance at room temperature to study the semiconductor compound CuAlO2 with a delafossite crystal structure, and we have determined the quadrupole frequency νQ = 28.12 MHz and the asymmetry parameter η ~ 0, which we used to study the features of the electron density distribution in the vicinity of the quadrupolar nucleus. In order to take into account...
The results of studying the nuclear spin-lattice relaxation of the nuclear spins of 63,65Cu in the CuAlO2 semiconductor compound (T = 77, 300 K) by the method of nuclear quadrupole resonance of Cu are presented. The relaxation rates in the CuAlO2 compound contain contributions from the magnetic and quadrupole relaxation mechanisms. The magnetic contribution to the relaxation rate is caused by hyperfine...
