Helical-to-Fan Transitions under Magnetic Fields in the Noncentrosymmetric Tetragonal Magnet EuRhGe${}_3$

Takeshi Matsumura, Hiroto Nitta, Hironori Nakao +4

The magnetic structure of EuRhGe${}_3$, a noncentrosymmetric body-centered tetragonal magnet with the space group $I4mm$, has been investigated by resonant X-ray diffraction. Below $…
