摘要： An improved surface acoustic wave device includes a film of a magnetostrictive material disposed on a substrate and spaced apart input and output transducer elements disposed on the film. The input element causes horizontally polarized shear waves to propagate along the film via the magnetostriction of the film. The shear waves propagating along the film are received by the output transducer element. The SAW device can be integrated on a microelectronic circuit useable in single chip radio frequency applications.

摘要： The specification describes silicon MOS devices with gate dielectrics having the composition Ta1−xAlxOy, where x is 0.03-0.7 and y is 1.5-3, Ta1−xSixOy, where x is 0.05-0.15, and y is 1.5-3, and Ta1−x−zAlxSizOy, where 0.7>x+z>0.05, z

摘要： A ferrite layer formation process that may be performed at a lower temperature than conventional ferrite formation processes. The formation process may produce highly anisotropic structures. A ferrite layer is deposited on a substrate while the substrate is exposed to a magnetic field. An intermediate layer may be positioned between the substrate and the ferrite to promote bonding of the ferrite to the substrate. The process may be performed at temperatures less than 300° C. Ferrite film anisotropy may be achieved by embodiments of the invention in the range of about 1000 dyn-cm/cm3 to about 2×106 dyn-cm/cm3.

摘要： The present invention is a planar spiral inductor a top magnetic layer a bottom magnetic layer; and a plurality of conductive coils disposed between said top magnetic layer and said bottom magnetic layer. A significant difference from prior art is that the top and bottom magnetic layers have their centers effectively cut out using lithographic techniques or other techniques to frame the core of the conductive spirals. An advantage of this structure over the prior art is that when magnetic anisotropies other than shape are kept small, then the magnetic configuration will produce a magnetostatic shape anisotropy such that the easy axis (low energy direction of magnetization) lies parallel to the legs of a rectangular frame or the circumference of a circular frame, as will be described. During operation of the inductor, the field produced by the coils flows in a radial direction and will be perpendicular to the easy axis direction thereby causing magnetization reversal to occur by rotation while advantageously utilizing the full structure in this mode.
摘要翻译：本发明是一种平面螺旋电感器，一个顶部磁性层，一个底部磁性层; 以及设置在所述顶部磁性层和所述底部磁性层之间的多个导电线圈。与现有技术的显着差异在于，使用光刻技术或其他技术来使顶部和底部磁性层有效地切出它们的中心以构成导电螺旋的芯。与现有技术相比，该结构的优点是当除形状之外的磁各向异性保持较小时，则磁性构型将产生静磁形状各向异性，使得容易轴（磁化强度的低能量方向）平行于矩形框架或圆形框架的圆周，如将要描述的。在电感器工作期间，由线圈产生的磁场在径向方向上流动并且将垂直于易轴方向，从而通过旋转而产生磁化反转，同时有利地利用该模式中的全部结构。

摘要： The invention is embodied in an anisotropic, soft magnetic thin film article comprising a cobalt-iron-chromium-nitrogen (Co--Fe--Cr--N) alloy. The thin film is formed such that the alloy has a relatively high saturation magnetization (4.pi.M.sub.s), e.g., greater than approximately 8 kilogauss (kG), a relatively low coercivity (H.sub.c), e.g., less than approximately 2.0 oersteds (Oe), a relatively high squareness ratio (M.sub.r /M.sub.s), e.g., greater than approximately 0.90, and a relatively high anisotropy field (H.sub.k), e.g., greater than approximately 20 Oe, in an as-deposited condition or, alternatively, with a relatively low temperature treatment, e.g., below approximately 300.degree. Celsius. The inventive films are suitable for use in electromagnetic devices, e.g., in microtransformer cores, inductor cores and in magnetic read-write heads.

摘要： Embodiments of the invention include a transformer device having a saturation region for limiting ingress noise and other noise. The transformer comprises a magnetic core, an input coil and an output coil arranged so that the output signal caused by the magnetic linkage between the input and output coils through the magnetic core is based on the magnitude of the input signal. According to an embodiment of the invention, the magnetic core includes a saturation region that limits the output signal regardless of the magnitude of the input signal once the saturation region reaches its saturation magnetization state. The saturation region comprises a reduced saturation magnetization level caused by a geometrically constricted region of the magnetic core or, alternatively, by a modified, magnetic-equivalent region having properties similar to a geometrically constricted region.
