Abstract: A ferromagnetic-polymer composite material comprises a polymer and a plurality of ferromagnetic film platelets disposed in the polymer. Each ferromagnetic film platelet comprises first and second insulator layers and a ferromagnetic layer disposed between the first and second insulator layers. The ferromagnetic layer can be magnetically anisotropic in which a hard axis of magnetization is aligned parallel to a plane that passes through and parallel to an interface between the first insulator layer and the ferromagnetic layer. The easy and/or hard axes of magnetization in the ferromagnetic film platelets can be aligned. An inductor can have a core formed of the ferromagnetic-polymer composite material.

Abstract: A planar magnetic core includes multiple ferromagnetic layers including multiple hard ferromagnetic bias layers and multiple soft ferromagnetic layers. Each ferromagnetic layer comprises a soft ferromagnetic layer or a hard ferromagnetic bias layer. Each hard ferromagnetic bias layer is a neighboring ferromagnetic layer of at least one soft ferromagnetic layer. The planar magnetic core also includes a plurality of insulating layers, each insulating layer disposed between adjacent ferromagnetic layers. Each ferromagnetic layer has an easy axis of magnetization parallel to a principal plane of the planar magnetic core, where the easy axes of magnetization are aligned. Each hard ferromagnetic bias layer is magnetized to create an in-plane bias magnetic flux through the hard ferromagnetic bias layer in a first direction that is parallel to the easy axis of magnetization and forms a closed path through a neighboring soft ferromagnetic layer in a second direction parallel to the first direction.

Abstract: A ferromagnetic actuator is disposed between first and second semiconductor devices that include first and second inductors. Each inductor is disposed on top of a multilevel wiring structure. Current flows through the first inductor to generate a first magnetic field that attracts the ferromagnetic actuator towards the first inductor causing the ferromagnetic actuator to transition from a first state to a second state. In the second state, a portion of the ferromagnetic actuator is disposed closer to the first inductor than it is in the first state. Current flows through the second inductor to generate a second magnetic field that attracts the ferromagnetic actuator towards the second inductor causing the ferromagnetic actuator to transition from the first or second state to a third state. In the third state, a portion of the ferromagnetic actuator is disposed closer to the first inductor than it is in the first state.

Abstract: An inductor includes a magnetic core lying in a core plane. The magnetic core includes a vertical laminated structure with respect to the core plane of alternating ferromagnetic vertical layers and insulator vertical layers. An easy axis of magnetization can be permanently or semi-permanently fixed in the ferromagnetic vertical layers along an axis orthogonal to the core plane. Methods of manufacturing same are also disclosed.

Abstract: An inductor includes a planar laminated magnetic core and a conductive winding. The planar magnetic core includes an alternating sequence of a magnetic layer and a non-magnetic layer. The non-magnetic layer includes an insulating layer that is disposed between first and second interface layers. The conductive winding turns around in a generally spiral manner on the outside of the planar laminated magnetic core. The inductor can be integrated into a multilevel wiring network in a semiconductor integrated circuit to form a microelectronic device, such as a transformer, a power converter, or a microprocessor.

Abstract: Inductive elements comprising anisotropic media and biasing coils for magnetically biasing thereof and methods of manufacture and operation for use in applications such as microelectronics. Application of an electrical current through the bias coils generates a magnetic field that biases the magnetic material such that a desirable orientation of anisotropy is achieved throughout the magnetic core and enables modulation of the inductive response of the device. Electrical conductors coupled to interconnects are magnetically coupled to magnetic core layers to produce self and/or mutual inductors.

Abstract: Methods of manufacture of integrated multi-layer magnetic films for use in passive devices in microelectronic applications. Soft ferromagnetic materials exhibiting high permeability and low coercivity are laminated together with insulating layers interposed. Electrical conductors coupled to interconnects are magnetically coupled to magnetic film layers to engender an inductor (self and mutual). Soft ferromagnetic materials are provided in an alternating array of parallel plate capacitors. Each alternating magnetic film is electrically coupled to either a primary or secondary electrical conductor interconnects and separated by an electrically insulating dielectric material. Alternatively, each alternating magnetic layer comprises an induced anisotropy material, which can also be combined with coiled conductor giving rise to a hybrid inductive/capacitive device. Also, soft ferromagnetic material are also selected and tuned to provide for FMR notch filtering.
