Phonon Activity and a Possible Lattice Arrangement in the Intermediate Phase of YVO3

Nestor E. Massa, Cinthia Piamonteze, Helio C. N. Tolentino +3

We show that in YVO3 new hard phonons gradually become zone center active below ~210 K verifying that a lattice phase transition takes place at about that temperature. The Debye-Wa…
