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…
Evolution of Helimagnetic Correlations when approaching the Quantum Critical Point of MnFeSi
Catherine Pappas, Andrey O. Leonov, Lars J. Bannenberg +3
We present a comprehensive investigation of the evolution of helimagnetic correlations in MnFeSi with increasing doping. By combining polarised neutron scattering and h…
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…
Reorientations, relaxations, metastabilities and multidomains of skyrmion lattices
L. J. Bannenberg, F. Qian, R. M. Dalgliesh +7
Magnetic skyrmions are nano-sized topologically protected spin textures with particle-like properties. They can form lattices perpendicular to the magnetic field and the orientatio…
