A self-consistent systematic expansion is developed for the t-1 model in the Schwinger-boson approach. We treat the fermion part with use of a systematic loop expansion technique and study the eR'ects of magnetic fluctuations on the normal-state properties. It is found that the hole motion is strongly renormalized and incoherent bands are produced by magnetic fluctuations. The conductivity and the electron density of states are calculated and shown to be anomalous. The antiferromagnetic nature

... f fluctuations is found to be essential for these unusual properties. The relevance of the obtained results to oxide superconductors is also discussed.
