Metal clusters, transition magnetic moments measurements

We focused on the size-selected cluster ions with small sizes in the above. On the other hand, the magnetic moments of neutral transition metal clusters in the size range between several and several hundreds are successfully measured by deflection in an inhomogeneous magnetic field. This method is basically the same as the Stern-Gerlach experiment known by the discovery of the electron spin by using the deflection of an atomic beam of silver. 

Figure 6.8 Results for the shell structure of the magnetic moment /xa of (a) Fe, (b) Co and (c) Ni clusters as a function of the number N of cluster atoms. A bcc-cube for Fe clusters, an fcc-cube for Ni clusters and an fcc-octahedron for Co clusters is assumed. The solid curves are calculated assuming a statistical shell-by-shell growth of the cluster. Only cluster structures with completely filled atomic shells are considered. For Fe the values /Xat = 4.0/xb, /Xsurf = 3.0/xb and /Xbuik = 2.21/xb for Co /Xat = 3.0/xb, /Xsurf = 1-9/xb and /Xbuik = 1.72/xb and for Ni /Xat = 1.2/xb, /Xjjurf = 0.7/xb and /Xbuik = 0.62/xb are used. The dashed curves are calculated with magnetic moments /x(z, ) which depend on the number of nearest neighbors qi of lattice site /, see Ref. [24]. The stars refer to measurements of transition metal clusters [ 19, 20]...
