摘要： A fluid transport system that includes a magnetic shape memory pipe having an input end opposite an output end and an outer surface opposite an inner surface. The inner surface defines an inner diameter of the magnetic shape memory pipe and the magnetic shape memory pipe includes a magnetic shape memory alloy. The fluid transport system further includes one or more magnetic field generating devices surrounding the outer surface of the magnetic shape memory pipe and configured to generate a control magnetic field that, when applied to a region of the magnetic shape memory pipe, alters the inner diameter of the region of the magnetic shape memory pipe.

摘要： A packaging structure with a magnetocaloric material, comprising a substrate, a plurality of electrical connection structures, a die, and a sealing compound. A magnetocaloric material is added to the substrate. The die is electrically connected to the substrate through the electrical connection structures, and then encapsulated with the sealing compound. When the packaging structure is turned on, the magnetocaloric material in the substrate creates a magnetocaloric effect, which can not only take away the temperature of the packaging structure through magnetic refrigeration, but also increase the temperature difference between the packaging structure and the outside, thereby improving the efficiency of heat dissipation.

摘要： A magnetic device comprising having a first magnetic layer having a first magnetization direction, a second magnetic layer having a second magnetization direction, a first coupling layer interposed between the first and second magnetic layers, a third magnetic layer having a third magnetization direction, a first magnetoresistive layer interposed between the third magnetic layer and the second magnetic layer, and a circuit connected to one or more of the layers of the magnetic device by at least a pair of leads. The circuit is configured to determine a change in resistance between the pair of leads. The change in resistance is based at least in part on a change in an angular relationship between the third magnetization direction and the second magnetization direction caused by an external magnetic field or a current passing through at least a portion of the device.

摘要： Provided is a group of rare-earth regenerator material particles having an average particle size of 0.01 to 3 mm, wherein the proportion of particles having a ratio of a long diameter to a short diameter of 2 or less is 90% or more by number, and the proportion of particles having a depressed portion having a length of 1/10 to ½ of a circumferential length on a particle surface is 30% or more by number. By forming the depressed portion on the surface of the regenerator material particles, it is possible to increase permeability of an operating medium gas and a contact surface area with the operating medium gas.

摘要： An article for magnetic heat exchange includes a functionally-graded monolithic sintered working component including La1-aRa(Fe1-x-yTyMx)13HzCb with a NaZn13-type structure. M is one or more of the elements from the group consisting of Si and Al, T is one or more of the elements from the group consisting of Mn, Co, Ni, Ti, V and Cr and R is one or more of the elements from the group consisting of Ce, Nd, Y and Pr. A content of the one or more elements T and R, if present, a C content, if present, and a content of M varies in a working direction of the working component and provides a functionally-graded Curie temperature. The functionally-graded Curie temperature monotonically decreases or monotonically increases in the working direction of the working component.

摘要： The instant invention relates to a magnetocaloric material based on NdPrFe17 melt-spun ribbons. This material has improved properties when compared with other similar magnetocaloric (MC) materials since it has an enhanced refrigeration capacity in the room temperature range due to its broader magnetic entropy change as function of the temperature curve. This material is useful as magnetic refrigerant as a part of magnetocaloric refrigerators.

摘要： A series of solid solutions AlFe2_xMnxB2 have been synthesized by arc-melting and characterized by powder X-ray diffraction, and magnetic measurements. All the compounds adopt the parent AlFe2B2-type structure, in which infinite zigzag chains of B atoms are connected by Fe atoms into [Fe2B2] slabs that alternate with layers of Al atoms along the b axis. The parent AlFe2B2 is a ferromagnet with Tc=282 K. A systematic investigation of solid solutions AlFe2_xMnx.B2 showed a non-linear change in the structural and magnetic behavior. The ferromagnetic ordering temperature is gradually decreased as the Mn content (x) increases. The substitution of Mn for Fe offers a convenient method for the adjustment of the ferromagnetic ordering temperature of AlFe2B2.

摘要： A current limiting device including a transformer including an element made from a magnetothermal material, a primary conductor, and a secondary winding. Heat is generated by the current flowing through the primary conductor and when the current exceeds a certain threshold it modifies the coupling coefficient of the transformer, which makes it possible to limit the current in the primary conductor.
