A team of scientists, led by University of Illinois physicist Peter Schiffer, has reported direct visualization of
magnetic charge crystallization in an
artificial spin ice material, a first in the study of a relatively new class of frustrated
artificial magnetic materials - by - design known as «
Artificial Spin Ice.»
«Our work is the first success achieving an
artificial ice of
magnetic charges with controllable energy states,» said Xiao, who holds a joint appointment between Argonne and NIU.
