We summarize the main novel features of almost localized fermions in tle presence of au applied magnetic field: (i) the spin dependence of their effective mass, wlich leads to quantum beats in the de Haas-van AIphen effect and (ii) the presence of a nonlinear molecular fleld and related metamagnetic behavior.
