Phase separation in paramagnetic Eu0.6La0.4-xSrxMnO3

We investigate the magnetic properties of the system Eu0.6La0.4-xSrxMnO3 with 0.1 <= x <= 0.3 by means of magnetic susceptibility and electron spin resonance measurements. Ferromagnetic resonance signals are observed in the paramagnetic regime from above the magnetic ordering temperature T-N up to approximately room temperature. This regime is characterized by the coexistence of ferromagnetic entities within the globally paramagnetic phase. The results are compared to the Griffiths scenario reported in La1-xSrxMnO3.
