Abstract
A magnetostatic wave device includes a ferrimagnetic base such as an YIG (yttrium, iron, garnet) thin film. This ferrimagnetic base is formed, for example, on a GGG (gadolinium, gallium, garnet) substrate. Furthermore, a disk-form conductor is formed on the YIG thin film. This conductor is formed by adhering, for example, copper foil to the YIG thin film or by adhering a conductive material such as silver to the YIG thin film surface by means of evaporating or sputtering method.
