Abstract
The magnetic properties of a decorated Ising system with a random field at the decorated atom are investigated by the use of the effective-field theor y with correlations. In particular, the phase diagram and magnetization cur ve of the decorated ferrimagnetic honeycomb lattice are examined numericall y. We find a lot of characteristic features in them, such as the possibilit y of two compensation points and the reentrant phenomenon. (C) 1999 Elsevie r Science B.V. All rights reserved.
