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…
The modulated antiferromagnetic structures in multiferroic FeVO4: a 57Fe Mössbauer spectroscopy investigation
D. Colson, A. Forget, P. Bonville
We present a 57Fe Mössbauer spectroscopy study of the two incommensurate magnetic phases in the multiferroic material FeVO4. We devise lineshapes appropriate for planar elliptical…
Room temperature coexistence of large electric polarization and magnetic order in BiFeO3 single crystals
Delphine Lebeugle, Dorothee Colson, Anne Forget +4
From an experimental point of view, room temperature ferroelectricity in BiFeO3 is raising many questions. Electric measurements made a long time ago on solid-solutions of BiFeO3 w…
Magnetic ordering in Gd2Sn2O7: the archetypal Heisenberg pyrochlore antiferromagnet
A. S. Wills, M. E. Zhitomirsky, B. Canals +4
Low-temperature powder neutron diffraction measurements are performed in the ordered magnetic state of the pyrochlore antiferromagnet Gd2Sn2O7. Symmetry analysis of the diffraction…
Transition and spin dynamics at very low temperature in the pyrochlores Yb2Ti2O7 and Gd2Sn2O7
P. Bonville, J. A. Hodges, E. Bertin +10
The very low temperature properties of two pyrochlore compounds, Yb2Ti2O7 and Gd2Sn2O7, were investigated using an ensemble of microscopic and bulk techniques. In both compounds, a…
