    Abstract: A substrate and a target are disposed within a vacuum chamber, and an oxygen partial pressure within the vacuum chamber is set to 1×10−5 or less. Under this condition, a spinel ferrite thin film selected from the group consisting of compounds represented by the formula AE1+tFe2−2tTMtO4, where AE represents an alkaline earth metal or an alkali metal, TM represents a transition metal and t falls within a range of between 0.2 and 0.6, and compounds represented by the formula Zn1−xCoxFe2O4, where x falls within a range of between 0.2 and 0.7, is deposited on the substrate by laser beam deposition. The particular method makes it possible to provide a spinel ferrite thin film realizing a spin glass state under temperatures around or higher than room temperature and capable of controlling the spin state by light.

    Abstract: The method of manufacturing rare earth thick film magnet comprising a step of forming an alloy layer of 30-100 nullm thick having a general formula RXBYTMZ on a substrate by a physical deposition process, and a step of heat-treating the alloy layer to form a thick film magnetic layer having R2TM14B phase as a main phase. In the general formula, R is at least one of rare earth elements, B is boron, TM is iron or its alloy partly substituted by cobalt. X is 0.1-0.2, Y is 0.05-0.2 and Znull1nullXnullY. Further, the method of the present invention includes a step of laminating a plurality of alloy layers formed on a substrate together with the substrate. A motor comprising rare earth thick film magnet of the present invention is extremely small while obtaining high output.

    Abstract: A production method of the present disclosure includes: a first step of preparing a multi-layer graphene, and an iron oxide that is a ferromagnetic material contacting the graphene and containing Fe3O4; and a second step of applying a voltage or a current between the graphene and the iron oxide with an electric potential of the graphene being positive relative to that of the iron oxide, so as to oxidize a part of the graphene or oxidize a part of the graphene and a part of Fe3O4, and thus to form a barrier layer composed of oxidized graphene or of oxidized graphene and Fe2O3 between the graphene and the iron oxide, and thereby forming a spin injection electrode that includes the graphene, the iron oxide, and the barrier layer located at an interface between the graphene and the iron oxide, and that allows spins to be injected into the graphene from the iron oxide via the barrier layer.
