Emergent topological spin structures in a centrosymmetric cubic perovskite
S. Ishiwata, T. Nakajima, J. -H. Kim +18
The skyrmion crystal (SkX) characterized by a multiple-q helical spin modulation has been reported as a unique topological state that competes with the single-q helimagnetic order…
Competing exchange interactions on the verge of a metal-insulator transition in the two-dimensional spiral magnet SrFeO
J. -H. Kim, Anil Jain, M. Reehuis +12
We report a neutron scattering study of the magnetic order and dynamics of the bilayer perovskite SrFeO, which exhibits a temperature-driven metal-insulator transition…
Magnetic phase diagram of
D. C. Peets, J. -H. Kim, P. Dosanjh +5
Magnetometry, electrical transport, and neutron scattering measurements were performed on single crystals of the Fe^{4+}-containing perovskite-related phase Sr_3Fe_2O_7-x as a func…
Complex Spin Structures and Origin of the Magneto-Electric Coupling in YMn2O5
J. -H. Kim, S. -H. Lee, S. I. Park +12
By combining neutron four-circle diffraction and polarized neutron diffraction techniques we have determined the complex spin structures of a multiferroic, YMn2O5, that exhibits tw…
