manganite

It can be shown that doping rare-earth is a effective measure to change the Curie temperature of Perovskite manganite and increase MR;

结果表明:稀土离子掺杂是改变钙钛氧化物里温度和增强MR的有效途径;

Pyrolusite,cryptomelane,coronadite,psilomelane,nsutite manganese spar,manganite and manganocalcite were found in the E′rentaolegai silver deposit.

额仁陶勒盖银床出现的物主要为软、、六方、铅、钾、菱、铁菱及方解石。

The composition, technique and characters about the manganite based NTC thermistor materials were reviewed in this paper.

摘要本文对含尖晶石系列热敏电阻材料的组成、制备工艺和性能给予了评述。
