The spin wave circuit that the researchers built, consists of a 200 nanometre thin layer of
yttrium iron garnet (a mineral and magnetic insulator, YIG in short), with a conducting platinum strip on top of that on both sides.
To do so, the researchers coupled the platinum to a layer of a magnetic insulator, a material known as
yttrium iron garnet.
Not exact matches
These range from a few micrograms (e.g. gold, indium, lutetium), or more than a milligram (e.g. zinc, scandium,
yttrium, niobium, gadolinium), to more than a gram per day (e.g. phosphorus,
iron, sulphur).
In 2006, condensation in a ferromagnetic
yttrium -
iron - garnet thin film was seen even at room temperature, [23][24] with optical pumping.
