摘要：

We have calculated the spin susceptibility of small metallic particles as a function of temperature, taking into account both effects of the finite energy-level spacing and the surface state allowing the electron tunneling among these electronic levels. The calculated magnetic susceptibility at low temperatures shows large enhancement due to the surface state in comparison with Pauli paramagnetism. This behavior is in good agreement with the peculiar temperature dependence of the susceptibilities of the reported divalent small metallic particles measured by the electron-spin-resonance method. © 1990 The American Physical Society.
