摘要：

Electromagnetic generation of sound in the heavy fermion systems CeRu2Si2 and UPt3 is investigated. Two coupling mechanisms are identified: Grüneisen parameter coupling and Lorentz force coupling. The latter mechanism can be used to determine experimentally the skin effect penetration depth. Some special effects in UPt3 are mentioned. © 1989.
