| A cold head is disposed in an insulating container and cooled by a refrigerator. A superconductor is disposed in the insulating container, contacting the cold head, and is cooled to its superconduction transition temperature or lower by heat conduction. A magnetizing coil is disposed outside the insulating container for applying a magnetic field to the superconductor. Control is performed so that a magnetic field determined considering the magnetic field to be captured by the superconductor is applied. A pulsed magnetic field is applied to the superconductor a plurality of times. Each pulsed magnetic field is applied when the temperature of the superconductor is a predetermined temperature or lower. A maximum pulsed magnetic field is applied at least once in an initial or intermediate stage of the repeated application of pulsed magnetic fields. After that, a pulsed magnetic field equal to or less than the maximum pulsed magnetic field is applied. Pulsed magnetic fields are repeatedly applied while the temperature of the superconductor is lowered. A pulsed magnetic field is applied when the temperature T0 of a central portion of the superconductor is the superconduction transition temperature or lower and the temperature of a peripheral portion is higher than T0. The temperature of the entire superconductor is brought close to T0 to apply another pulsed magnetic field. The magnetizing coil faces at least one of two opposite sides of the superconductor to apply pulsed magnetic fields to the superconductor in its magnetization direction. | ||||||

| 233 | Magnetically enhanced convection heat sink | US10684104 | 2003-10-07 | US20050073814A1 | 2005-04-07 | Brian Tillotson |
| A magnetically enhanced convection heat sink comprises a heat sink member for dissipating heat from a heat source. A magnetic source creates a magnetic field concentrated at a first location, the intensity of the magnetic field decreasing from the first location to a second location. The heat sink member is positioned within the magnetic field and in a gas flow path between the first and second locations. Gas, having paramagnetic properties, entering the heat sink at the first location is heated by the heat sink member, and as the gas becomes warmer is displaced by cooler gas causing the warmer gas to move toward the second location as it is further heated by the heat sink. | ||||||
| 234 | Method for providing transverse magnetic bias proximate to a pole tip | US10628646 | 2003-07-28 | US20050024177A1 | 2005-02-03 | Quan-Chiu Lam |
| A method for providing transverse magnetic bias proximate to a pole tip to speed up the switching time of the pole-tip during the writing operation is disclosed. The transverse field disposed proximate the pole-tip helps the conventional driving field in rotating the magnetization through the first 90-degrees, especially at small angle where the effective anisotropy-field is strongest in opposing the conventional driving field. By offsetting the magnetization from its easy-axis, the transverse field also increases the torque that the collinear driving field would have on the magnetization. | ||||||

| 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 &mgr;m, 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. | ||||||
