摘要：

Tunneling conductance measurements of the electronic density of states of perovskite manganates, La(0.7)A(0.3)MnO(3) are reported. Tunneling data of all the samples show a zero-bias anomaly with a minimum in the density of states at the Fermi level. This behavior is interpreted as arising from strong electronic correlations.
