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.
