Abstract
LaNi(1-x)FexO3 is metallic for x less than or equal to 0.3 and an anti ferromagnetic insulator for x = 1. As a consequence, the EPR spectrum undergoes important changes as a function of x. The high-temperature l inewidth is independent of T only for x greater than or equal to 0.7. In the other cases the linewidth is a linear function of T with an x-d ependent slope. Relaxation mechanisms are discussed.
