EPR and Magnetization Studies on the 'Two Electron Doped' Manganite Ca_(1_x)Ce_xMnO_3

摘要

The "two-electron" doped rare earth manganite Ca_(1-x)Ce_xMnO_3~1 (0 <= x <= 0.2) shows rich and interesting magnetic and electronic properties as a function of temperature and composition. For low compositions it shows a G-type Antiferromagnetic (AFM) phase and for x>=0.1 it shows two magnetic phases along with charge ordering (CO). One is C-type AFM and the other is 'magnetic charge ordered' (MCO) phase. To study these complex magnetic phases EPR is an ideal local probe.
