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矿锰氧化物居里温度和增强mr的有效途径;
chapter 1: the general review of the history and present research situation of the perovskite manganite physics and thin films is given.
第一章全面介绍了巨磁阻锰氧化物的物理和薄膜的研究状况。
more recently, the perovskite manganite compounds, a1-xbxmno3 have received much attention because of their gigantic magnetoresistance (gmr) and charge ordering properties.
近几年来,这类钙钛矿型结构的氧化物材料因为其具有的巨磁电阻效应受到了更多的关注。
as we know, the studies of perovskite manganite oxides have attracted much renewed attention in strongly correlated electron system since the discovery of colossal magnetoresistance(cmr) effect.
正如我们所知道的,自从在钙钛矿锰氧化物中发现巨磁电阻效应以来,有关它的研究已经成为当前强关联电子体系的一个研究热点。
