Phys. Rev. Lett. 84, 761–764 (2000)55Mn NMR Investigation of Electronic Phase Separation in La1-xCaxMnO3 for 0.2 ≤ x ≤ 0.5Received 20 May 1999; published in the issue dated 24 January 2000 55Mn NMR line shape measurements in La1-xCaxMnO3 for 0.20≤x≤0.50 provide experimental evidence about the existence of two distinct regions in the T-x magnetic phase diagram, where the homogeneous ferromagnetic (FM) metallic state is separated into FM metallic and FM insulating regions. These results are in agreement with recent theoretical predictions, which reveal a novel electronic phase separation in two FM states, providing orbital ordering and Jahn-Teller phonons are taken into consideration. © 2000 The American Physical Society URL:
