Rotational magnetoelastic interactions in the Dzyaloshinskii-Moriya magnet Ba${}_2$CuGe${}_2$O${}_7$

J. Sourd, T. Kotte, P. Wild +3

We report the magnetoelastic properties of a Ba${}_2$CuGe${}_2$O${}_7$ single crystal at low temperatures under a magnetic field applied along the crystallographic [001] axis. Our result…
