$|1-\nu|$ increases. This has been observed in nuclear magnetic resonance (NMR) experiments. [@general; @Barrett; @Fertig] On the other hand, the $\nu=1$ state of non-interacting disordered electrons differs qualitatively. The ground state is a compressible paramagnet with no Knight shift and no gap for charged excitations. For zero Zeeman coupling, quasiparticle states at the Fermi energy are quasi-extended and cause the Hall conductivity to suddenly jump by $2 e^2/h$ as this filling factor is crossed; $\nu=1$ is in the middle of a Hall ‘riser’, instead of being at the middle of a Hall plateau. The competition between disorder and interactions at $\nu=1$ can be addressed[@olderhfdis] using the Hartree-Fock approximation which has the virtue of being exact[@general] in both the non-interacting and the non-disordered limits. Experimental information on this competition comes primarily from transport and NMR studies. Early NMR studies[@Barrett] of weak-disorder quantum Hall ferromagnets, yielded relatively featureless lineshapes and Knight shifts in good agreement with Hartree-Fock (HF) theory estimates[@Fertig; @Brey; @Cote] of Zeeman-coupling and filling-factor dependent Skyrmion sizes. (Effective field theory estimates[@Sondhi; @Rajaraman] are not accurate in the case of typical Zeeman coupling strengths.) More recent experiments[@Barrett_private] paint a more complex picture, in part because the measurements were performed at lower
