Optical study of the cooperative Jahn-teller distortion in DyVO 4 and DyAsO 4
Abstract
The changes of refractive indices during the crystallographie phase transitions in DyVO 4 and DyAsO 4 have been measured. There is a significant difference between the two substances. The phase transition is continuous in DyVO 4 but first order in DyAsO 4.
