Abstract
The detailed analysis of de Haas-van Alphen effect, one of magneticoscillation phenomena in metallic materials, is given for the free electron system, and the mechanism for its occurrence is reviewed. This effect may be veryinteresting for applications to the engineering field. However, unfortunately, since the observations are limited to only the liquid Helium temperature for thepresent available external magnetic field, it may be difficult at the present stageto apply the effect to the engineering. In future, if we can make the four timeslarger magnetic field, the effect can easily happen at the room temperature.Good applications of this effect in future are hoped.
