GALVANOMAGNETIC STUDIES IN METALS BY MEANS OF HELICONLIKE WAVES

This paper delineates the materials in which magnetoplasma waves in metals can be used to measure elements of the resistivity tensor. Results from the noble metals and from Al and In are discussed. The strengths and weaknesses of the wave method are discussed and compared with standard direct-current experimental methods. The magnetoplasma wave which was used is called the helicon in simple isotropic solids and is called the Whistler wave in ionospheric physics. The agreement between measurements of the anisotropy of resistivity tensor elements in copper as measured by this heliconlike-wave technique and those made by dc magnetoresistivity studies is very good. © 1968 The American Physical Society.
