Programming of Complex Magnetic Profiles Enforced by 4D Printed Magnetic LCE Actuators

Advanced Materials, EarlyView.
A 4D printing‐enabled magnetic programming strategy is introduced in which thermally actuated liquid crystal elastomers are magnetized in their target shape to encode complex three‐dimensional magnetic profiles. The resulting actuators achieve multistate shape morphing and programmable locomotion under low magnetic fields, without requiring specialized

Atomic‐Scale Detection of Néel Vector Switching in the Single‐Layer A‐Type Antiferromagnet Cr2S3‐2D

Advanced Materials, EarlyView.
Interfacial electron donation from graphene redistributes charge within single‐layer Cr2S3‐2D, preferentially accumulating at the lower Cr/S plane. The resulting minute magnetic imbalance lifts the equivalence of the two magnetic sublayers, enabling atomic‐resolution identification and field‐induced control of Néel‐vector states in a two‐dimensional A ...
