The islands were lithographically printed onto a substrate, arranged
in a square - lattice pattern, with the north and south poles of each
nanomagnet meeting and interacting at their four - pronged vertices.
Spin transfer torque is the transfer of the spin angular momentum from conduction electrons to the magnetization of a ferromagnet and enables the manipulation of
nanomagnets with spin currents rather than magnetic fields,» explained Gyung - Min Choi, who recently completed his PhD
in materials science and engineering at Illinois.
Los Alamos National Laboratory staff scientist Cristiano Nisoli explained, «The emergence of magnetic monopoles
in spin ice systems is a particular case of what physicists call fractionalization, or deconfinement of quasi-particles that together are seen as comprising the fundamental unit of the system,
in this case the north and south poles of a
nanomagnet.
In this research, iron - nickel nanomagnets were fabricated in shakti arrays, a structure with 2, 3, and 4 nanomagnet islands meeting in periodic arrays (resulting in vertexes with 2, 3, and 4 coordination numbers
