摘要：
A Raman-scattering investigation of the double-layer manganites, La2-2xSr1+2xMn2O7 (x = 0.4, 0.5), revealed signatures of a) charge stripe formation and melting, b) small polaron formation, and c) anisotropic quasiparticle dynamics in the ferromagnetic-metallic state. These observations and their implications are discussed in this work.
