LCMO-PMMA nanostructured composites have been synthesized by a unique polymeric sol-gel route, which leads to improved solubility of PMMA in the LCMO matrix. The LCMO phase is grown in the presence of varying PMMA concentration at ~500 ^0 C. This route yields single phase material and the grain size is observed to decrease slightly with increasing PMMA concentration. On increasing the PMMA concentration, T_C undergoes a small decre","authors_text":"H. K. Singh, Jitendra Kumar, N. D. Kataria, O. N. Srivastava, P. K. Siwach, Rajiv K.
