Determination of the Hall coefficient by direct generation of ultrasound

A theoretical study is made of the generation of ultrasound as a function of an applied, static magnetic field for propagation along a (110) direction in a potassium crystal. For certain orientations of the incident radiofrequency field the variation of acoustic amplitude with field presents a cusp....

Description
Summary:A theoretical study is made of the generation of ultrasound as a function of an applied, static magnetic field for propagation along a (110) direction in a potassium crystal. For certain orientations of the incident radiofrequency field the variation of acoustic amplitude with field presents a cusp. The position of this min. can be used to determine the departure of the Hall coefficient from its free-electron value. 14 ref.--AA
