Among the electronic properties of metallic fine particles, the phenomena associated with the interparticle electron transfer are not yet well understood. For example, the temperature dependence of granular films often shows clear deviation from that of the activation type, which can be expected from a simple theory. In this respect, the charge neutrality and the quantum charge fluctuations of fine particles are very important problems, and the studies on those problems will be reviewed mainly from theoretical perspectives.

The One

The temperature dependence of spin currents in insulators at the finite temperature near zero Kelvin is theoretically studied. The spin currents are carried by Jordan–Wigner fermions and magnons in one- and three-dimensional insulators. These spin currents are generated by the external magnetic field gradient along the quantization axis and also by the two-particle interaction gradient. In one-dimensional insulators, quantum fluctuations are strong and the spin current carried by Jordan–Wigner fermions shows the stronger dependence on temperatures than the one by magnons.

Granular Films

Simulation of thin granular films and twolayer structures is carried out by Monte Carlo methods. Temperature dependence of equilibrium macroscopic characteristics of granular films such as magnetization, energy, heat capacity, and magnetic susceptibility are calcu-lated for different linear sizes of granules. Influence of exchange integral values for inter-action between granules in film and interlayer interaction in twolayer structure is studied.
