摘要： The present invention provides a magnetostrictive member with high performance, high reliability and high versatility. The magnetostrictive member is used in the vibration power generation as a power source for extracting electric energy from various vibrations. The member made of the single crystal is manufactured cheaper than the conventional manufacturing method. The magnetostrictive member is formed by cutting a single crystal of Fe—Ga alloy by using electric discharge machining in a state that orientation of the crystal of the Fe—Ga alloy is aligned in a direction in which magnetostriction of the magnetostrictive member is required.

摘要： A method for producing a magnetostrictive material and a method for increasing the value of magnetostriction can increase the value of magnetostriction of magnetostrictive materials used, for example, in vibration power generation and force sensors utilizing inverse magnetostriction phenomenon. A magnetostrictive material having a value of magnetostriction of 100 ppm or more is produced by melting and casting an alloy material in the composition of range of 67-87 wt % Co with the balance consisting of Fe and unavoidable impurities and then performing hot forging. Furthermore, a magnetostrictive material having a value of magnetostriction of 130 ppm or more can be produced by performing cold rolling after the hot forging. Heat treatment at 400-1000° C. may also be performed after hot working or cold working.

摘要： Apparatus and methods are disclosed that enable writing data on, and reading data of, multi-state elements having greater than two states. The elements may be made of magnetoplastic and/or magnetoelastic materials, including, for example, magnetic shape-memory alloy or other materials that couple magnetic and crystallographic states. The writing process is preferably conducted through the application of a magnetic field and/or a mechanical action. The reading process is preferably conducted through atomic-force microscopy, magnetic-force microscopy, spin-polarized electrons, magneto-optical Kerr effect, optical interferometry or other methods, or other methods/effects. The multifunctionality (crystallographic, magnetic, and shape states each representing a functionality) of the multi-state elements allows for simultaneous operations including read&write, sense&indicate, and sense&control. Embodiments of the invention may be used, for example, for storing, modifying, and accessing data for device, sensor, actuator, logic and memory applications. Embodiments may be particularly effective for non-volatile memory or other read&write, sense&indicate, and/or sense&control functions in computer or other applications; such simultaneous operation of two (or more) of said multiple functionalities open new pathways for miniaturization of devices.

摘要： A membrane actuator includes a magnetically actuatable membrane and a magnetic trigger. The membrane includes a shape memory alloy (SMA), and the magnetic trigger is configured to induce a martensitic transformation in the SMA, to produce a larger force than would be achievable with non-SMA-based materials. Such a membrane actuator can be beneficially incorporated into a wide variety of devices, including fluid pumps, shock absorbing systems, and synthetic jet producing devices for use in an aircraft. The membrane/diaphragm can be formed from a ferromagnetic SMA, or a ferromagnetic material can be coupled with an SMA such that the SMA and the ferromagnetic material move together. A hybrid magnetic trigger, including a permanent magnet and an electromagnet, is preferably used for the magnetic trigger, as hybrid magnetic triggers are easy to control, and produce larger magnetic gradients than permanent magnets or electromagnets alone.
