The macroscopic features of the behavior of a mesoscopic particle in a
magnetic field are investigated for mesoscopic particles possessing t
he properties of a semimetal or a nonmagnetic insulator. It is shown t
hat for a fixed value of the magnetic field the frequency of the Alfve
n magnetoplasma mode falls off monotonically (as 1/R) as the radius of
the particle increases. (C) 1997 American Institute of Physics. [S106
