Researchers at the RIKEN Center for Emergent Matter Sciences , Ochanomizu University and other institutes worldwide recently examined the low-energy excitations of skyrmions hosted in manganese monosilicide , an intermetallic material that has proved promising for spintronics applications. Their paper, published in, reports the observation of asymmetric slow dynamics in the material's skyrmion lattice.
"Particularly, due to their ability to be controlled with minimal energy expenditure, offering low-power consumption and high-density implementation, they hold promise for applications in non-volatile memory. In fact, their energy scale was reported to be a few orders of magnitude smaller than that required to drive conventional magnetic domains.
"It is of great significance for research in the field that experimental evidence confirms the predictions made by theorists," Kawano-Furukawa said."The skyrmions in our crystal have a 'handedness' like a screw, so the +z and -z directions should behave somewhat differently, like the head and tail of a screw.
