Abstract

Correlation of the temperature dependences of Raman scattering and ferromagnetic resonance is found in nanowires of a dilute magnetic semiconductor Ge0.99Co0.01. 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.
