Adv Mater. 2015 Jan 7;27(1):86-92. doi: 10.1002/adma.201403836. Epub 2014 Nov 18.

Abstract

A new type of magnetochromatic material is developed based on thin-film interference of microplates self-assembled from super-paramagnetic nanocrystals. Dynamic optical tuning can be achieved through orientational manipulation of free-standing super-paramagnetic thin-film microplates using external magnetic fields.

Keywords: dynamic modulation; magnetochromatic; microplates; nanocrystals; self-assembly; thin-film interference.
