Abstract:We have fabricated highly sensitive micromechanical cantilever magnetometers and, by this means, investigated the de Haas-van Alphen effect of a two-dimensional electron system in a modulation-doped Si/SiGe heterostructure. As a function of perpendicular magnetic field component B ⊥ we observe at low temperature sawtooth-like oscillations of the magnetization M. These are found at even integer filling factors ν = n s /(eB ⊥ /h) = 4(N + 1) with N = 0, 1, 2..., when the chemical potential is in the Landau energy… Show more
