[J-4-01 (Invited)]From spin-orbitronics to orbitronics:
efficient manipulation of topological spin structures for memory and unconventional computing
〇Mathias Kläui1,2(1. Johannes Gutenberg-Universität Mainz (Germany), 2. NTNU Trondheim (Norway))
Novel spintronic devices can play a role in the quest for GreenIT. Devices have been proposed, where switching by energy-efficient approaches is used [1,2].
We combine ultimate stability of topological states due to chiral interactions [3,4] with ultra-efficient manipulation using novel spin torques [3-5] and orbital torques [6].
We use skyrmion dynamics for non-conventional stochastic computing [7,8] and synthetic antiferromagnets are promising for high performance [9,10].
