Phonon activity and intermediate glassy phase of YVO₃

We show that in YVO₃ additional hard phonons gradually become zone center infrared active below ∼210 K, verifying that a lattice phase transition takes place at about that temperature. Their gradual increment in intensity between ∼210 and ∼77 K is associated with a "glassy" behavior found...
