When magnetic materials are nanometric at least in one
dimension, the surface effect often dominates the static and
transport behaviors due to the limited long-range order and broken
translation symmetry. The perturbations in spin-spin correlation
length and unperfect spin coordination structures make
low-dimensional magnetic materials an ideal platform for exploring
magnetism in reduced dimensions. Low dimension materials,
especially those in two-dimensions (2-D) pose a conceptual flatland
for mechanically flexible, engineerable and biocompatible devices
with complex functionalities via a patterning or assembling manner
to integrated objects.
