Long period helical structures and twist-grain boundary phases induced by non magnetic ion doping in Mn(Co,Rh)Ge chiral magnet
N. Martin, M. Deutsch, G. Chaboussant +6
We study the evolution of helical magnetism in MnGe chiral magnet upon partial substitution of Mn for non magnetic 3d-Co and 4d-Rh ions. At high doping levels, we observe spin heli…

Magnetic ground state and spin fluctuations in MnGe chiral magnet as studied by Muon Spin Rotation
N. Martin, M. Deutsch, F. Bert +9
We have studied by muon spin resonance (μSR) the helical ground state and fluctuating chiral phase recently observed in the MnGe chiral magnet. At low temperature, the muon polariz…

Magnetovolume effect, macroscopic hysteresis and moment collapse in the paramagnetic state of cubic MnGe under pressure
N. Martin, I. Mirebeau, M. Deutsch +6
Itinerant magnets generally exhibit pressure induced transitions towards non magnetic states. Using synchrotron based X-ray diffraction and emission spectroscopy, the evolution of…
