Abstract

We calculated the nuclear spin-lattice relaxation rate in the (formula presented) system and found that the orbital relaxation mechanism dominates over the dipolar and Fermi-contact mechanisms in (formula presented) whereas in (formula presented) due to a smaller density of states and strong anisotropy of boron p orbitals the relaxation is completely determined by Fermi-contact interaction. The results for (formula presented) are compared with existing experimental data. To validate the theory, nuclear resonance experiments for the studied diboride alloy system are needed.
