Skyrmion lattice in a chiral magnet.
Skyrmions represent topologically stable field configurations with particle-like properties. We used neutron scattering to observe the spontaneous formation of a two-dimensional lattice of skyrmion lines, a type of magnetic vortex, in the chiral itinerant-electron magnet MnSi. The skyrmion lattice stabilizes at the border between paramagnetism and long-range helimagnetic order perpendicular to ...
متن کاملReversible “triple-Q” elastic field structures in a chiral magnet
The analytical solution of the periodic elastic fields in chiral magnets caused by presence of periodically distributed eigenstrains is obtained. For the skyrmion phase, both the periodic displacement field and the stress field are composed of three "triple-Q" structures with different wave numbers. The periodic displacement field, obtained by combining the three "triple-Q" displacement structu...
متن کاملCritical phenomena of emergent magnetic monopoles in a chiral magnet
Second-order continuous phase transitions are characterized by symmetry breaking with order parameters. Topological orders of electrons, characterized by the topological index defined in momentum space, provide a distinct perspective for phase transitions, which are categorized as quantum phase transitions not being accompanied by symmetry breaking. However, there are still limited observations...
متن کاملA chiral-based magnetic memory device without a permanent magnet
Several technologies are currently in use for computer memory devices. However, there is a need for a universal memory device that has high density, high speed and low power requirements. To this end, various types of magnetic-based technologies with a permanent magnet have been proposed. Recent charge-transfer studies indicate that chiral molecules act as an efficient spin filter. Here we util...
متن کاملAchiral single molecule magnet and chiral single chain magnet.
An achiral molecular square and a chiral chain composed of cyanide bridged Fe(III) and Ni(II) ions were prepared, and they act as a single molecule magnet and a chiral single chain magnet, respectively.
