Resumen

We present electron spin resonance (ESR) data at 9.4 GHz in the phase separated Pr_0.65Ca_0.25Sr_0.10MnO₃ manganite. The coexistence of two resonance lines are observed below the short-range magnetic-order temperature (T_s≈255K). One of the ESR line is a paramagnetic contribution retained from the high-temperature phase. The second contribution appears at T_s, which is associated with the presence of ferromagnetic regions. The two contributions can be seen near the charge-order transition, 7_co≈210K. We study the temperature evolution of the resonance field and the linewidth of the ESR lines.
