| 142 | Process for obtaining a thin, insulating, soft magnetic film of high magnetization | US11189028 | 2005-07-25 | US07504007B2 | 2009-03-17 | Guillaume Bouche; Pascal Ancey; Bernard Viala; Sandrine Couderc |
| A thin soft magnetic film combines a high magnetization with an insulating character. The film is formed by nitriding Fe-rich ferromagnetic nanograins immersed in an amorphous substrate. A selective oxidation of the amorphous substrate is then performed. The result is a thin, insulating, soft magnetic film of high magnetization. Many types of integrated circuits can be made which include a component using a membrane incorporating the above-mentioned thin film. | ||||||

| 144 | Magnetoresistive medium including nanowires | US11078405 | 2005-03-14 | US07459222B2 | 2008-12-02 | Igor Shvets; Sunil Kumar Arora; Sumesh Sofin Ramakrishna Pilli |
| A magnetoresistive medium (1) includes a substrate (2) which has been treated to provide a miscut vicinal surface (3) in the form of terraces (4) and steps (5) of atomic and nanometer scale. There are discrete separated spacer nanowires (7) provided by an intermediate partial spacer film on each terrace (4) against each step (5). A further main film (11) provides main nanowires (10(a), 10(b)). A thin protective layer (15) covers the main nanowires (10(a), 10(b)) which form two separate subsets of main nanowires with different exchange interaction with the substrate and thus a different response to an external magnetic field. In use, when an external magnetic field (H) is applied the response of the main nanowires (10(a), 10(b)) changes as the exchange coupling with the substrate (2) varies and the magnetisation on the main nanowires (10(a), 10(b)) change. This is shown by the arrows while prior to the application of the external magnetic field, they might, for example, be aligned. Many different constructions of magnetoresistive media are described. | ||||||

| A magnetic thin film with a high resonant frequency and superior high-frequency characteristics, and a magnetic device and an inductor with superior high-frequency characteristics are provided. A planar coil and a magnetic thin film are disposed on a substrate, and an inductor is formed between connection terminals. An obliquely-grown magnetic layer in the magnetic thin film is crystal-grown in an oblique direction with respect to a surface of the substrate (an obliquely-grown magnetic body). In order to make the obliquely-grown magnetic body exhibit soft magnetism in the obliquely-grown magnetic layer, an insulator is mixed into the obliquely-grown magnetic body. The obliquely-grown magnetic layer shows in-plane magnetocrystalline anisotropy, and the in-plane magnetocrystalline anisotropy is increased, and an anisotropic magnetic field is increased. The anisotropic magnetic field can be changed only by a crystal growth direction of the obliquely-grown magnetic layer, so without reducing saturation magnetization, the anisotropic magnetic field can be increased, and the resonant frequency of the magnetic thin film can be improved. | ||||||

| A laminated magnetic thin film has a laminated structure in which insulating layers and granular layers are formed alternately on a substrate. The insulating layers are formed of SiO2 films. The granular layers are formed of FeNiSiO films and have a structure in which an insulator is present in grain boundaries so as to wrap magnetic particles. It is possible to improve insulating properties of the insulating layers and the insulators and increase resistivity thereof by heating the substrate at the time of film formation. It is possible to control deterioration of a magnetic characteristic due to an increase in a resistivity and realize both a high magnetic characteristic and a high resistivity by changing thicknesses of the insulating layers and the magnetic layers and a ratio of the magnetic particles to the insulator to optimize a diameter of the magnetic particles having a composition within a predetermined range. | ||||||
