Abstract
Phases in the system Cu3+xSi were analyzed by temperature-dependent x-ray powder diffraction and differential scanning calorimetry on samples with nominal composition Cu74Si26 and Cu78Si22 in the temperature range between 30 °C and 700 °C. Contrary to previous works, which report three phases in the system, we identified six distinct phases, labeled, in order of increasing temperature, ηâ´, ηâ³, ηâ², η3, η2, η1. All these phases can be indexed with a similar basic unit cell. However, each phase has a different superstructure or modulation vectors.
