    摘要： Glassy alloys containing cobalt, nickel and iron and evidencing near-zero magnetostriction and high saturation induction are disclosed. The glassy alloys consist essentially of about 13 to 73 atom percent cobalt, about 5 to 50 atom percent nickel, about 2 to 17 atom percent iron, with the proviso that the total of cobalt, nickel and iron is about 80 atom percent, and the balance essentially boron plus incidental impurities. The magnetostriction of the glassy alloys ranges from about +3.times.10.sup.-6 to -3.times.10.sup.-6 and the saturation induction is at least about 8 kGauss.

    摘要： Magnetically-controlled actuator materials are provided that produce large actuation stroke, that exhibit fast actuation response time and corresponding high-frequency operation, and that enable efficient actuation energy conversion at convenient operating temperatures. The actuator materials exhibit an austenitic crystal structure above a characteristic phase transformation temperature and exhibit a martensitic twinned crystal structure below the phase transformation temperature. One actuator material provided by the invention is an alloy composition that can be defined generally as (Ni.sub.a Fe.sub.b Co.sub.c).sub.65-x-y (Mn.sub.d Fe.sub.e Co.sub.f).sub.20+x (Ga.sub.g Si.sub.h Al.sub.i).sub.15+y, where x is between about 3 atomic % and about 15 atomic % and y is between about 3 atomic % and about 12 atomic %, and where a+b+c=1, where d+e+f=1, and g+h+i=1. The actuator material is characterized by a magnetocrystalline anisotropy energy that is sufficient for enabling motion of twin boundaries of the martensitic twinned crystal structure in response to application of a magnetic field to the martensitic twinned crystal structure. This enables the material to produce an actuation stroke in response to the magnetic field. Based on this actuation mechanism, the actuator materials of the invention overcome the thermal, stroke, and frequency response limitations typically associated with actuator materials, and enable a class of actuators with large stroke and high speed at convenient temperatures.

    摘要： A self-biasing magnetostrictive element for use in a magnetomechanical EAS marker is a strip of amorphous alloy with crystalline particles of semi-hard or hard magnetic material distributed throughout the bulk of the amorphous alloy strip. The crystalline particles are magnetized to bias the amorphous alloy strip to resonate in response to an interrogation signal. The crystalline particles are formed by heat-treating the amorphous alloy strip at a temperature above the Curie temperature of the amorphous alloy in the presence of a longitudinal magnetic field. The alloy strip is then cross-field annealed at a temperature below the Curie temperature of the amorphous alloy to form a transverse anisotropy in the amorphous bulk of the alloy strip. A preferred alloy composition includes iron, cobalt, niobium, copper, boron and silicon.

    摘要： Apparatus and method for harvesting energy from the environment and/or other external sources and converting it to useful electrical energy. The harvester does not contain a permanent magnet or other local field source but instead relies on the earth's magnetic field of another source of a magnetic field that is external to the sensing device. One advantage of these new harvesters is that they can be made smaller and lighter than energy harvesters that contain a magnet and/or an inertial mass.
