摘要：

A random-bond ferroelectric model is analyzed employing the effective Hamiltonian method extended to random systems. The critical properties are investigated considering both competing and noncompeting interactions. At this aim the uniform, staggered and spin-glass susceptibilities are introduced and the Curie, Néel and spin-glass transition temperatures determined. The phase diagram is constructed and the role of the model parameters emphasized. © 1990, Taylor & Francis Group, LLC. All rights reserved.
