Magnetic manipulation of self-assembled colloidal asters
Alexey Snezhko,Igor S. Aranson +1 more
TL;DR: It is shown that a magnetic colloidal suspension confined at the interface between two immiscible liquids and energized by an alternating magnetic field dynamically self-assembles into localized asters and arrays of asters, which exhibit locomotion and shape change.
Journal ArticleDOI
Self-assembled magnetic surface swimmers.
TL;DR: It is found that the symmetry of the surface flows can also be broken in a controlled fashion by attaching a large bead to a magnetic snake (bead-snake hybrid), transforming it into a self-locomoting entity.
Journal ArticleDOI
Flocking ferromagnetic colloids
TL;DR: Primary physical mechanisms leading to the emergence of large-scale collective motion are identified: spontaneous symmetry breaking of the clockwise/counterclockwise particle rotation, collisional alignment of particle velocities, and random particle reorientations due to shape imperfections.
Journal ArticleDOI
Rewritable artificial magnetic charge ice
Yong-Lei Wang,Yong-Lei Wang,Zhili Xiao,Zhili Xiao,Alexey Snezhko,Jing Xu,Jing Xu,Leonidas E. Ocola,Ralu Divan,John E. Pearson,G. W. Crabtree,Wai-Kwong Kwok +11 more
TL;DR: An artificial spin structure that produces a magnetic charge ice with tunable long-range ordering of eight different configurations is designed and a technique to precisely manipulate the local magnetic charge states is developed, which could provide a setting for designing magnetic monopole defects, tailoring magnonics, and controlling the properties of other two-dimensional materials.
Journal ArticleDOI
Driving self-assembly and emergent dynamics in colloidal suspensions by time-dependent magnetic fields.
James E. Martin,Alexey Snezhko +1 more
TL;DR: This review discusses various methods of driven self-assembly in magnetic suspensions subjected to alternating magnetic fields, and some of the remarkable properties of these novel materials are described.
