Resumen:
LaNi(1-x)FexO3 is metallic for x < 0.3 and an antiferromagnetic insulator for x = 1. As a consequence, the EPR spectrum undergoes important changes as a function of x. The high-temperature linewidth is independent of T only for x > 0.7. In the other cases the linewidth is a linear function of T with an x-dependent slope. Relaxation mechanisms are discussed.
