Abstract

Studies of low-frequency resistance noise show that the glassy freezing of the two-dimensional electron system (2DES) in Si in the vicinity of the metal-insulator transition (MIT) persists in parallel magnetic fields B of up to 9 T. At low B, both the glass transition density n_g and n_c, the critical density for the MIT, increase with B such that the width of the metallic glass phase (n_c < n_s < n _g) increases with B. At higher B, where the 2DES is spin polarized, n_c and n_g no longer depend on B. Our results demonstrate that charge, as opposed to spin, degrees of freedom are responsible for glassy ordering of the 2DES near the MIT.
