摘要：

The anomalous low resistivity metallic material at room temperature has been discovered. Known high resistive material called manganin in form of 10 mu m thick foil was one side implanted with high dose of niobium ions of 2.5 x 10(17) Nb ions/cm(2) and then with 2.5 x 10(13) Kr ions/cm(2). Before and after implantation procedure investigated manganin foils were temperature treated in 130 degrees C during 100 h. Basic resistance measurements were performed just after implantation observing large decrease of its resistivity. In repeated measurements after long time later (about twelve months), at temperature of 22 degrees C, practically no resistivity was measured. Four-terminal method for resistance measurements was used.
