    • 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.
    • 公开了能够对具有大于两个状态的多状态元件进行数据写入和读取数据的装置和方法。 元件可以由磁性和/或磁弹性材料制成,包括例如磁性形状记忆合金或耦合磁性和晶体状态的其它材料。 写入过程优选通过施加磁场和/或机械动作来进行。 读取过程优选通过原子力显微镜,磁力显微镜,自旋极化电子,磁光克尔效应,光学干涉测量或其他方法或其它方法/效果进行。 多状态元件的多功能(每个表示功能的结晶学,磁学和形状状态)允许包括读取和写入,感测和指示以及感测和控制的同时操作。 本发明的实施例可以用于例如用于存储,修改和访问设备,传感器,致动器,逻辑和存储器应用的数据。 实施例对于非易失性存储器或计算机或其它应用中的其它读/写,感测和指示和/或感测和控制功能可能是特别有效的; 两个(或多个)所述多个功能的这种同时操作打开用于设备小型化的新途径。
