Equation of State of Zircon-Type $TbVO_{4}$

High-pressure energy-dispersive X-ray diffraction study were performed on zircon-type phase of terbium orthovanadate, $TbVO_{4}$, in the pressure range up to 7 GPa. For analysis of the collected diffraction spectra, Le Bail refinements were performed. The values of bulk modulus and its pressure derivative ($B_0$ = 121 GPa, B' = 4.1) were obtained from fitting of the second-order Birch-Murnaghan equation of state. The equation of state derived for $TbVO_{4}$, is compared with earlier data based on the Raman spectroscopic studies and with data of several other rare-earth orthovanadates.
