Structural evolution with temperature and magnetoelastic coupling across the TN in the rare-earth chromites family

The main objective of this proposal is to study the structural evolution of rare-earth chromites RCrO3 (R = Sm, Eu, Gd, Tb, Dy, Ho, Lu) from 4 K to 1073 K. We will study their behavior through the magnetic transition to observe possible magnetoelastic effects and we will investigate the temperature evolution of several structural features, such as the superexchange angle, to understand their behavior above room temperature, a temperature interval barely explored in the past.
