Epitaxial Permalloy with Unique Magnetic Properties

IntroductionThe need for improvements in sensitivity, performance and reduction in size of magnetoresistive devices, such as non-volatile magnetoresistive random access memory (MRAM) and magnetic sensors, is the driving force behind the search for new magnetic materials. The switching characteristics, homogeneity of magnetic domains, magnetic anisotropy...

Prestrained Thin-Film Shape Memory Actuators Offer Rapid, Strong Response

Introduction Prior use of thin films of SMA materials has been confined to the deposition of films onto rigid substrates such as silicon, limiting their use to planar elements which are not amenable to the pre-straining required to obtain maximum shape memory strain recovery. Prior SMA cyclic actuator systems using wires, springs or sheets require...
