Magnetic field induced modification of the incommensurate antiferromagnetic structure of Fe-doped MnNiGe alloys
The evolution of the magnetic structure of Fe-doped MnNiGe alloys of nominal compositions ${\mathrm{MnNi}}_{0.75}{\mathrm{Fe}}_{0.25}\mathrm{Ge}$ and ${\mathrm{Mn}}_{0.85}{\mathrm{Fe}}_{0.15}\mathrm{NiGe}$ has been probed through neutron powder diffraction (NPD) experiments in the presence of external magnetic fields ($H$). Application of external $H$ results in a significant decrease in the antiferromagnetic satellite peak's intensities along with a considerable change in the incommensurate propagation vector ${\mathbit{k}}_{\mathrm{AFM}}=({k}_{a},0,0)$. In addition, a reasonable increase in some of the nuclear reflections has also been noticed, which can clearly be described by the ferromagnetic propagation vector ${\mathbit{k}}_{\mathrm{FM}}=(0,0,0)$. Our analysis confirms the gradual rotation of magnetic moments towards the $a$ axis with increasing $H$ and eventual realization of ferromagnetic arrangement at higher applied $H$.
