This effect is measured either through the field modulation method or the torque method, and its general form can be expressed using the Dingle temperature and adding a cosine term for the Zeeman effect in the Lifshitz- Kosevich formula. Observing this effect requires a cyclotron orbit smaller than the mean free path, and Onsager proved that this effect is proportional to A to the negative 2, which is why this effect is used in high-field laboratories to measure the areas of Fermi surfaces. This effect can be understood as a slight fluctuation in the gap between Landau levels, leading to one fewer of them being filled. It is the counterpart of an effect that sees oscillations in resistivity, named for Shubnikov and one of this effect's namesakes. For 10 points, name this doubly-eponymous effect in which the magnetic susceptibility of a system oscillates in respon
