摘要
The mechanism explaining the key role of AFM correlations in formation of the heavy fermion state is offered. It is shown that in the case of the critical spin fluctuations transform the mean-field second-order transition to RVB state into the crossover from high-temperature paramagnetic behavior of localized spins to strongly correlated spin liquid with quasi itinerant character of susceptibility. Thus the spin liquid state {\it by its origin} is close to magnetic instability, so either short-range or long-range AFM order should arise at low T.
