Abstract
X-ray diffraction measurements and Raman spectroscopy at room temperature document the equation of state and the frequency shifts for Eg, T2g, and A1g vibrational modes of polycrystalline LaB6 under pressure. The data exhibit smooth pressure dependencies, yielding a zero-pressure isothermal bulk modulus K0T=164(± 2) GPa in good accord with independent ultrasonic measurements, and show no evidence of structural or electronic phase transitions up to at least 25 GPa.
