In the present work we report the electron spin resonance(ESR) and magnetic measurements to understand the effect of grain size on the charge ordering (CO), orbital ordering (OO), long range anti ferromagnetic (AFM) ordering in Bi{sub 0.67}Ca{sub 0.33}MnO{sub 3} manganite synthesized by sol-gel method. The temperature dependence of linewidth (ΔH) of the ESR signal and magnetization have been used to get information about magnetic interactions. The CO is suppressed and AFM ordering remains unaffected with increase in grain size of the sample. The competition between FM and AFM correlations is strongly dependent on the grain size of the sample.
