A low energy beam of spin polarized 8Li has been used to study the behaviour of isolated 8Li implanted into a 150 nm thick film of Al on an MgO substrate. The spin relaxation rate 1 / T 1 and β -NMR lineshape were measured as a function of temperatu

A low energy beam of spin polarized 8 Li + has been employed to study the magnetic field distribution in an epitaxial thin film of 5.4% Mn doped GaAs(180nm) on a (100) GaAs substrate via beta-detected NMR. The spectrum is a strong function of the imp

We report the modification to the linear temperature dependence of the Korringa nuclear spin-lattice relaxation rate of an implanted NMR probe in silver, as it makes a thermally activated site change. We develop a simple model of this phenomenon, whi

We report �-NMR investigations of polarized 8 Li implanted in thin Pb and Ag/Nb films. At the critical superconducting temperature, we observe a singular peak in the spin relaxation rate in small longitudinal magnetic fields, which is attributed to

Level-crossing resonances are observed for spin-polarized ${}^{8}$Li in copper at 200 K. The positions of the resonances as a function of magnetic field and crystal orientation are a precise measure of the induced quadrupolar interaction on the neare

The temperature dependence of the frequency shift and spin-lattice relaxation rate of isolated, nonmagnetic Li-8 impurities implanted in a nearly ferromagnetic host (Pd) are measured by means of beta-detected nuclear magnetic resonance (b-NMR). The s

We report β -NMR measurements of the nuclear spin relaxation rate ( 1 / T 1 ) in a thin film of La0.67Ca0.33MnO3 (LCMO) using a low-energy beam of spin-polarized 8Li. In a small magnetic field of 150 G, there is a broad peak in 1 / T 1 near the Curi
