フェルミ面
After the 1950s, the DHVA effect gained wider relevance after Lars Onsager (1952), and independently, Ilya Lifshitz and Arnold Kosevich (1954), pointed out that the phenomenon could be used to image the Fermi surface of a metal. In 1954, Lifshitz and Aleksei Pogorelov determined the range of applicability of the theory and how described how to determine the shape of any arbitrary convex Fermi surface by measuring the extremal sections. Lifshitz and Pogorelov also found a relation between the temperature dependence of the oscillations and the cyclotron mass of an electron.
