Absence of Ferromagnetic Instability at the Metal-Insulator Transition in Si-inversion Layers

V. M. Pudalov, M. E. Gershenson, H. Kojima

We have measured the Shubnikov-de Haas oscillations in high-mobility Si MOS structures over a wide range of the carrier densities n > 0.77x10^{11}/cm^2. This range includes the cri…
