Large spin-phonon coupling and magnetically-induced phonon anisotropy in Sr$M$O${}_3$ perovskites ($M$=V,Cr,Mn,Fe,Co)

Jun Hee Lee, Karin M. Rabe

First-principles calculations reveal large zone-center spin-phonon coupling and magnetically-driven phonon anisotropy in cubic perovskites Sr$M$O${}_3$ ($M$=V,Cr,Mn,Fe,Co). In partic…
