摘要

研究了掺锶锰酸镧-钙钛矿在微波波段的磁共振特性。在烧结体试样中观察到一个宽的共振峰。对于薄膜试样，检测到两个共振峰。这一事实表明，在薄膜样品中存在一些磁子系统。其中一种磁化强度较低，达到饱和量级，在我们看来，这是一种低磁性的磁态。其他峰明显对应典型铁磁态。

Magnetoresonance features of strontium-doped lanthanum manganites-perovskites in microwave band

Magnetoresonance features of strontium-doped lanthanum manganites-perovskites in microwave band were investigated. One wide resonance peak has been observed for sintered bulk specimen. For thin-films specimens two resonance peaks has been detected. This fact shows that in thin-film specimens a few magnetic subsystems present. One of them has a low magnetization of saturation magnitude and corresponds to asperomagnetic magnetic state in our view. Other peak corresponds to typical ferromagnetic state apparently.
