摘要： A magnetic powder core comprises a molded article of a mixture of a glassy alloy powder and an insulating material. The glassy alloy comprises Fe and at least one element selected from Al, P, C, Si, and B, and has a texture primarily composed of an amorphous phase. The glassy alloy exhibits a temperature difference nullTx, which is represented by the equation nullTxnullTxnullTg, of at least 20 K in a supercooled liquid, wherein Tx indicates the crystallization temperature and Tg indicates the glass transition temperature. The magnetic core precursor is produced mixing the glassy alloy powder with the insulating material, compacting the mixture to form a magnetic core precursor, and annealing the magnetic core precursor at a temperature in the range between (Tgnull170) K and Tg K to relieve the internal stress of the magnetic core precursor. The glassy alloy exhibits low coercive force and low core loss.

The alloy can be cast by rapid solidification from the melt into ribbon, sheet or wire form. The alloy exhibits rounded or rectangular or sheared B-H hysteresis behaviors in its as-cast condition. The alloy is further annealed with or without magnetic field at temperatures below said alloy's first crystallization temperature, having rounded or rectangular or sheared or linear B-H hysteresis loops. The alloy is suited for magnetic applications especially at high frequencies.

摘要： The invention relates to a method and to a device for carrying out a manufacturing process in which all magnet cores to be produced are first continuously crystallized. Depending on whether the required hysteresis loops should be round, flat or rectangular, the magnet cores are either immediately finished, that is enclosed in housings, conditioned to a rectangular hysteresis loop in a direct-axis magnetic field or to a flat hysteresis loop in a magnetic cross-field and then finished.

摘要： A ferromagnetic resonator for use in a marker in a magnetomechanical electronic article surveillance system has improved magnetoresonant properties and/or reduced eddy current losses by virtue of being annealed so that the resonator has a fine domain structure with a domain width less than about 40 nullm, or less than about 1.5 times the thickness of the resonator. This produces in the resonator an induced magnetic easy axis which is substantially perpendicular to the axis along which the resonator is operated magnetically by a magnetic bias element also contained in the marker. The annealing which produces these characteristics can take place in a magnetic field of at least 1000 Oe, oriented at an angle with respect to the plane of the material being annealed so that the magnetic field has a significant component perpendicular to this plane, a component of at least about 20 Oe across the width of the material, and a smallest component along the direction of transport of the material through the annealing oven.

摘要： A metallic glass alloy ribbon consists essentially of about 70 to 87 atom percent iron. Up to about 20 atom percent of the iron is replaced by cobalt and up to about 3 atom percent of the iron is replaced by nickel, manganese, vanadium, titanium or molybdenum. About 13-30 atom percent of the element balance comprises a member selected from the group consisting of boron, silicon and carbon. The alloy is heat-treated at a sufficient temperature to achieve stress relief. A magnetic field applied during the heat-treatment causes the magnetization to point away from the ribbon's predetermined easy magnetization direction. The metallic glass exhibits linear DC BH loops with low ac losses. As such they are especially well suited for use in current/voltage transformers.
