Abstract

Magnetic susceptibility and EPR have been studied in a glass system xGd₂O₃ ·(20-x) · La₂O₃ · 22Al₂O₃ · 23B₂O₃ · 35(SiO₂+GeO₂) with x = 0.03, 0.35, 1.75 and 3.5mol%. Positive Weiss constants have been found in more heavily-doped glasses and ascribed to clustering of Gd³⁺ ions. In less-doped glasses the EPR spectra have a typical "U"-type shape; at higher doping levels the spectral features are broadened. Computer simulations show that in the latter case the spectra are superposition of signals arising from isolated ions and ferromagnetic clusters.
