Abstract:

Experimental and theoretical studies of the electromagnetic sound generation have been carried out in bismuth and gallium, resulting in a basic understanding of this effect. High field studies have contributed useful information on their electronic properties. Further studies have been made of the possible antiferromagnetic state of potassium. High resolution sound velocity instrumentation has been applied to studies of the magnetic properties of glasses alloys and crystals. Preliminary studies have been made of interactions of phonons with electrons in superconducting films. Author
