摘要

在稀磁半导体Ge0.99Co0.01的纳米线中，发现了拉曼散射和铁磁共振的温度依赖关系。在T≈74 K时，光学声子线突然“软化”。观察到的行为表明载流子不仅与声子相互作用，而且与磁系统相互作用强。

Raman Scattering in Ferromagnetic Ge1 – xCox Nanowires

Correlation of the temperature dependences of Raman scattering and ferromagnetic resonance is found in nanowires of a dilute magnetic semiconductor Ge_0.99Co_0.01. A sudden “softening” of optical phonon lines occurs at T ≈ 74 K. The observed behavior indicates a strong interaction of carriers not only with phonons but also with the magnetic system.
