Symko, Orest George | Calibration of SQUID magnetometer for dilute alloy studies | A SQUID magnetometer used in the study of dilute magnetic alloys or other weak magnetic systems can be calibrated by using the nuclear paramagnetism of aluminum metal. This material is useful as a calibration standard since magnetic impurities such as Fe and Mn form no local moment. This calibration... | SQUID magnetometer | 1979 |

Ailion, David Charles | NMR observations of molecular motions and Zeeman-quadrupole cross relaxation in 1,2- difluorotetrachloroethane | We report measurements of "F NMR relaxation times Tu Tlf, TID, and T2 in the plastic crystal CFCL2-CFCL2 . From the data near the melting point, we obtain the jump time for translational selfdiffusion. At lower temperatures, we observe on the cold side of the T, and Tif minima an unusual field depe... | NMR; Nuclear magnetic resonance; Order-disorder; Diffusion | 1979 |

Ailion, David Charles | Nuclear magnetic resonance study of diffusion of bound and free fluorine interstitials in alkaline earth fluorides doped with trivalent impurities | When alkaline-earth fluorides are doped with trivalent impurities, interstitial fluorines are created to maintain charge neutrality. We have performed NMR dipolar-energy relaxation measurements over a wide temperature range and have observed the diffusion of both free and locally bound fluorine inte... | Diffusion; Motion; Crystals; NMR; Fluorine | 1979 |

Ailion, David Charles | Zeeman-quadrupole cross relaxation between two nuclear spin species | We derive an expression for the rate T / s ' of the cross relaxation between the Zeeman splitting of one nuclear spin species (/ spins, I = 1/2) and the quadrupole splitting of another spin species ( 5 spins, S > 1/2) via the IS dipolar interaction. We calculate T , s for the case of CFCL2-CFCL2 (/ ... | Spin species; Spin-lattice relaxation | 1979 |
