Abstract The rich and extensively studied archaeological record of the Near East provides an opportunity to develop a comprehensive archaeomagnetic dataset for exploring the behavior of the geomagnetic field with high precision. The Levantine archaeo

Transport properties of the superprotonic conductor, CsHSO4, have been investigated by impedance spectroscopy and nuclear magnetic resonance (NMR). It has been found that both, conductivity (σ) and NMR diffusion (D NMR) are practically isotropic in

A general theory of spin-lattice nuclear relaxation of spins I=1/2 caused by dipole-dipole couplings to quadrupole spins S1, characterized by a non-zero averaged (static) quadrupole coupling, is presented. In multispin systems containing quadrupolar

By nuclear magnetic resonance spin-lattice relaxation dispersion in LaF3, measured in the frequency range from 60 kHz to 284 MHz, dynamic processes with correlation times in the range from 10-5 to 10-10 s are studied. This allows us to trace fluorine
