Abstract
An experimental determination has been made of the eddy current effects on the nuclear magnetic resonance lineshapes of Al²⁷ wires. Eddy currents in the metal result from the applied radio frequency (r-f) field used to obtain resonance. Due to the induced eddy currents, this r-f magnetic field is attenuated and its phase is shifted as it progresses toward the center of the sample. A quantity defined as the skin depth is a measure of this attenuation. As a result of the attenuation and phase shift of the r-f magnetic field, the resultant lineshape of a given mode of the resonance is determined by both the "pure" or undistorted absorption and dispersion modes: i.e., mixing of the modes occurs.
