在一种新开发的连续工作团簇源中制备了直径在12 nm数量级的质量过滤FeCo团簇，并沉积在硅表面。原子力显微镜的测量表明，自由粒子的高度小于直径，这可以用粒子-载体相互作用来解释。更大的团簇是由于静电四极杆中的质量选择过程，静电四极杆以不同的m/e比分开。用X射线磁性圆二色谱(XMCD)结合元素分析测定了其磁性能。(C)2004爱思唯尔B.V.保留所有权利。
Mass filtered FeCo clusters with diameters in the order of magnitude of 12 nm were prepared in a new developed, continuously working cluster source and deposited on a Si surface. The AFM measurements exhibit a height being smaller than the diameter for free particles which can be explained by particle-support interaction. Larger clusters are due to the mass selecting process in an electrostatic quadrupole which separates with different m/e ratios. Magnetic properties were determined by X-ray magnetic circular dichroism (XMCD) with elemental specification. (C) 2004 Elsevier B.V. All rights reserved.
