Field-induced vortex-like textures as a probe of the critical line in reentrant spin glasses
N. Martin, L. J. Bannenberg, M. Deutsch +4
We study the evolution of the low-temperature field-induced magnetic defects observed under an applied magnetic field in a series of frustrated amorphous ferromagnets (FeMn…
Onset of a skyrmion phase by chemical substitution in MnGe chiral magnet
E. Altynbaev, N. Martin, A. Heinemann +4
We study the evolution of the magnetic phase diagram of MnFeGe alloys with concentration () by small-angle neutron scattering. We unambiguously…
Spin Textures induced by Quenched Disorder in a Reentrant Spin Glass: Vortices versus "Frustrated" Skyrmions
I. Mirebeau, N. Martin, M. Deutsch +6
Reentrant spin glasses are frustrated disordered ferromagnets developing vortex-like textures under an applied magnetic field. Our study of a NiMn single crystal…
Disorder and Quantum spin ice
N. Martin, P. Bonville, E. Lhotel +7
We report on diffuse neutron scattering experiments providing evidence for the presence of random strains in the quantum spin ice candidate Pr2Zr2O7. Since Pr is a non-Kramers ion,…
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…
Field induced phase diagram of the XY pyrochlore antiferromagnet ErTiO
E. Lhotel, J. Robert, E. Ressouche +9
We explore the field-temperature phase diagram of the XY pyrochlore antiferromagnet ErTiO, by means of magnetization and neutron diffraction experiments. Depending on t…
