一维铁磁CMR/聚合物系统的基态性质研究

Research of One-Dimensional Ferrmagnetic CMR/in the System with Organic Ground State

对具有铁磁CMR/聚合物系统,采用一维紧束缚模型来研究基态时界面处的自旋极化现象.计算表明在铁 磁CMR/聚合物系统中极化子的产生能比单纯的聚合物系统中的极化子产生能低,这增加了聚合物材料中自旋极 化输运的可能性.

In the system with ferromagnetic CMR/polymer, with the one-dimensional tight-binding model the phenomena of spin polarization near the interface is studied. It is found that creation energy of polaron is lower in the system with ferromagnetic CMR/polymers than in the system with pure organic polymers, which can increase the possibility of spin polarization in polymer system.
