对羰基分解制备的铁纳米颗粒进行了结构、化学和磁性的比较。通过磁矩、透射电子显微镜观察到的颗粒大小和校准后的x射线荧光测定的总铁浓度，确定了颗粒的比磁化强度。报告了不同尺寸的颗粒和用略有不同的技术制成的颗粒的氧化物体积分数。
Fe nanoparticles prepared by iron carbonyl decomposition using different methods are compared structurally, chemically, and magnetically. The specific magnetization of the particles was determined from the magnetic moment, the particle size observed by transmission electron microscopy, and the total iron concentration found from calibrated X-ray fluorescence. The volume fraction of oxide is reported for particles of different sizes and for particles made by slightly different techniques.
