Monoclinic BiCrO 3, synthesized at high pressure and high temperature, presents interesting
properties with anomalies of magnetic origin observed around 110 and 80 K, which are
associated, respectively, with the rise of a G-type antiferromagnetic structure and the spin
reorientation along one of the monoclinic axes. In this study, we report a strong spin–phonon
coupling in monoclinic BiCrO 3 observed by Raman spectroscopy. The renormalization of
the phonon energy confirms the coupling with the magnetic orderings. Interestingly, some …
