Abstract
Low-field galvanomagnetic measurements have been made on gallium single crystals at 77°K and the eighteen independent coefficients specified in a phenomenological equation determined. The coefficients are highly anisotropic. The resistivities differ by a factor of 7.4, the Hall constants by a factor of 10.3, and the magnetoresistance coefficients differ by a factor of 160. The possibility of fitting a "many-valley" model to the data is considered but it is concluded that the use of this model is not appropriate for gallium.Keywords
