AbstractAbstract
[en] Using the Schwinger boson method, a detailed phase diagram of Manganese oxides at low temperatures is obtained. The magnetic transition and spin correlation are studied, based on an electron-electron correlation mechanism. The results indicate that there are antiferromagnetic (AF), spiral (SP), ferromagnetic (FM) and canted (CN) states when T→0. With temperature increasing, a paramagnetic (PM) state appears. The critical temperatures TD and TQ vary with the doping concentration. The spin-spin correlation function is also obtained
