Electron paramagnetic resonance and thermal behavior of NdP5O14 and LaP5O14

Abstract
The ferroelastic phase transition of LaP5O14 and NdP5O14 at, respectively, 403 and 428 K was analyzed by electron paramagnetic resonance and differential thermal analysis studies over the temperature range 210–450 K. Near room temperature, another thermal anomaly was clearly identified on both materials by these two methods.
