通过气相生长法合成了纳米氧化锰颗粒。纳米颗粒的直径可以通过生长温度来控制：温度越高，颗粒的直径越大。磁化强度测试结果表明，锰氧化物纳米颗粒具有明显的铁磁行为，居里温度在40 K左右。后者是尺寸依赖性的，即：颗粒的直径越小，居里温度越低。(C)2003 Elsevier B.V.保留所有权利。
Nanosized manganese oxide particles have been synthesized via vapor phase growth. The diameter of the nanoparticles can be controlled by the growth temperature: the higher the temperature, the larger the diameter of the particle. Magnetization measurements show that the manganese oxide nanoparticles have an obvious ferromagnetic behaviour with the Curie temperature around 40 K. The latter is size-dependent, namely: the smaller is the diameter of the particles, the lower is the Curie temperature. (C) 2003 Elsevier B.V. All rights reserved.
