Abstract

In-situ observation of inelastic light scattering of boson region in glassy Ba₂TiGe₂O₈ (BTG) was performed during heating process. The in-situ boson observation revealed structural relaxation below glass-transition temperature in the as-quenched sample, suggesting the nanometric structural heterogeneity. Relation of the boson behavior to crystallization tendency is also discussed.
