- Chromium dioxide (CrO_2) is the half metal with simplest structure whose spin polarization detected by Adreeve reflection reaches to 98.4% at the temperature of 77 K. These characters make it be a potential candidate for fabrication of MTJ devices. 二氧化铬(CrO_2)是结构最简单的一种半金属磁体; 77K 下用Adreeve 反射法测得其自旋极化率达到98.;4%25;与理论预言100%25的自旋极化率十分接近;这些特点使CrO_2 在磁电子学领域具有很好的应用前景。
