Patterned ferrimagnetic thin films of spinel ferrites obtained directly by laser irradiation [PDF]

open access: yes, 2013
Some spinel ferrites can be oxidized or transformed at moderate temperatures. Such modifications werecarried out on thin films of mixed cobalt copper ferrites and maghemite, by heating small regions with alow-power laser spot applied for about 100 ns ...
