摘要：

Using the break-junction tunneling technique in magnetic fields up to 20 T, a magnetic-field-induced cross over from a pseudogap to a metallic heavy-fermion state has been observed in CeNiSn. The pseudogap at the Fermi level which opens at T<10 K, was suppressed by a magnetic field applied along the a axis but was not affected for a field along the b axis.
