摘要
A La-139 NMR study was carried out on melt-grown samples of La1-xSrxMnO3 (0 less than or equal to x less than or equal to 0.15). The microscopic magnetic structure of the parent LaMnO3 was identified as a homogeneous antiferromagnet at low temperatures. Substituted compounds with x greater than or equal to 0.1 demonstrate the homogeneous ferromagnetic phase. Only a lightly doped sample with x = 0.05 shows the coexistence of NMR lines from ferromagnetic and antiferromagnetic phases. [S0163-1829(99)15901-0].
