摘要：

Static and dynamic properties of a diluted quasi-two-dimensional magnet NixMg1-x(OH)(2) have been investigated by the measurements of susceptibility and magnetization. The irreversible magnetization and its slow-relaxation phenomena are observed even above the Neel temperature of the diluted magnet. The experimental results suggest the existence of the Griffiths phase in NixMg1-x(OH)(2). (C) 1998 Elsevier Science B.V. All rights reserved.
