Formation of incommensurate long-range magnetic order in the Dzyaloshinskii-Moriya antiferromagnet Ba${}_2$CuGe${}_2$O${}_7$ studied by neutron diffraction

S. Mühlbauer, G. Brandl, M. Månsson +1

Neutron diffraction on a triple-axis spectrometer and a small-angle neutron scattering instrument is used to study the magnetic phase transition in tetragonal Ba${}_2$CuGe${}_2$O${}_7$ a…
