摘要：

Specimens of the form Ca1-xLaxMnO3 (0 less than or equal to x less than or equal to 0.2) are utilized to study the effect of electron doping on the magnetic saturation moment M-sat(5 K). The systematic behavior of M-sat(5 K) vs x is understood through a phenomenological model which suggests the existence of local ferromagnetic regions within the antiferromagnetic host for 0.03<x<0.08.
