%X We have performed magnetization measurements and electron spin resonance (ESR) on polycrystalline manganites of Ndmanganite, electron spin resonance, phase separationProject supported by the National Natural Science Foundation of China (Grant No 50672126) and the Inner Mongolia Natural Science Foundation of China (Grant No 200607010102).7530G, 7630, 7530V3/4/2008 12:00:00 AMWe have performed magnetization measurements and electron spin resonance (ESR) on polycrystalline manganites of Ndmanganite, electron spin resonance, phase separationProject supported by the National Natural Science Foundation of China (Grant No 50672126) and the Inner Mongolia Natural Science Foundation of China (Grant No 200607010102).7530G, 7630, 7530V3/4/2008 12:00:00 AMWe have performed magnetization measurements and electron spin resonance (ESR) on polycrystalline manganites of Nd$_{0.5}$Sr$_{0.5 - x}$Ba$_{x}$MnO$_{3}$ ($x = 0.1$). Phase separation and phase transitions are observed from the susceptibility and the ESR spectra data. Between 260\,K ($\sim T_{\rm C})$ and 185\,K ($\sim T_{\rm N})$, the system coexists of the paramagnetic phase and the ferromagnetic (FM) phase. Between 185\,K and 140\,K, the system coexists of the FM phase and the antiferromagnetic (AFM) phase. These results indicate that the system has a very complex magnetic state due to the origin of the instability stemming from manganite Nd$_{0.5}$Sr$_{0.4}$Ba$_{0.1}$MnO$_{3}$ by partially substituting the larger Ba$^{2 + }$ ions for the smaller Sr$^{2 + }$ ions.
