摘要： An object of the invention is to provide: an MgB2 superconducting thin-film wire that exhibits excellent Jc characteristics even under a 20 K magnetic field; and a method for producing thereof. The MgB2 superconducting thin-film wire includes a long substrate and an MgB2 thin film formed on the long substrate. The MgB2 thin film has a microtexture such that MgB2 columnar crystal grains stand densely together on the surface of the long substrate, and has Tc of 30 K or higher. In grain boundary regions of the MgB2 columnar crystal grains, a predetermined transition metal element is dispersed and segregated. The predetermined transition metal element is an element having a body-centered cubic lattice structure.

摘要： A method of embedding a magnetic component in a substrate is disclosed. Holes are formed in a substrate by mechanically drilling. Each of the holes includes a top opening, a bottom and sidewall, wherein an area of the top opening is larger than that of the bottom. The sidewall extends from the top opening vertically downwards to a predetermined depth, and then is slanted inwardly to the bottom to form a sloped sidewall at the bottom of the hole. A predetermined region is defined along a portion of an edge of the top opening, and a portion of the substrate material under the predetermined region is removed by routing to form a component accommodation trench with a portion of the sloped sidewall at the bottom. Then, a magnetic component is placed into the component accommodation trench.

摘要： A substrate having a pattern of magnetic properties may be formed by forming a magnetically inactive layer on the substrate, forming a magnetic precursor on the magnetically inactive layer, and forming magnetically active domains separated by magnetically inactive domains in the magnetic precursor by applying thermal energy to the magnetic precursor. The thermal energy may be applied using a laser, which may be pulsed. Forming the magnetically active domains may include crystallizing portions of the magnetic precursor.
