| 中文摘要 | Electron spin resonance (ESR) study was carried out on La(0.67)Ca(0.33)Mn(1-x)FexO(3) (x = 0.0, 0.04) samples. The temperature dependence of the ESR spectra indicates the presence of phase separation above and below T-C in x = 0.0 and 0.04 sample, respectively. The increase of the g-value in the high-temperature region indicates the existence of local spin correlations even in the paramagnetic state. The activation energy obtained from both the temperature dependence of the ESR intensity and linewidth exhibits a smaller value in the Fe-doped sample. Our study suggests that the ferromagnetic spin correlations would be significantly weakened by a slight doping of Fe ions on Mn sites. (C) 2008 Elsevier B.V. All rights reserved. |
