Abstract: A multilayered magnetic thin-film stack including a tunneling barrier layer; a magnetic finned layer formed on a first surface of the tunneling barrier layer; and a magnetic free layer formed on a second surface of the tunneling barrier layer, which is opposite to the first surface, wherein at least one of the magnetic finned layer and the magnetic free layer includes a FeZr alloy layer and a first magnetic layer having a (001) bcc structure between the FeZr alloy layer and the tunneling barrier layer.

Abstract: The present invention relates to a cobalt (Co) and platinum (Pt)-based multilayer thin film having a novel structure and perpendicular magnetic anisotropy, and to a fabrication method thereof. More specifically, the invention relates to a cobalt and platinum-based multilayer thin film having perpendicular magnetic anisotropy (PMA), which includes thin cobalt layers and thin platinum layers alternately deposited over a substrate, and has an inverted structure in which a thickness of the thin cobalt layers is greater than that of the thin platinum layers, and to a fabrication method thereof. The cobalt and platinum-based multilayer thin film has a new structure in which the thickness of a magnetic thin layer is greater than that of a non-magnetic thin layer. The multilayer thin film may be easily applied as a free layer and a pinned layer in a magnetic tunnel junction by controlling the perpendicular magnetic anisotropy energy depending on the thickness ratio of the layers.

Abstract: A method of extracting an Integrated Circuit (IC) current is provided. The method includes generating a transfer function value by using a voltage measured in a node nearest an input terminal of the IC, substituting the generated transfer function value for a reverse fast Fourier transform function, so as to extract the IC voltage, and extracting the IC current from the extracted IC voltage through a simulation in a time domain.

Abstract: An easily installable decoration tile is disclosed, whereby a plurality of tiles can be tightly and securely fastened by allowing the coupling lugs to be inserted into the coupling grooves, and allowing the rugged lugs to be inserted into the rugged grooves, to increase coupling force between tiles, to increase durability of the tiles after construction works are done, to dispense with use of adhesives and to free dwellers from being worried about hazards, and surfaces of coupling lugs and rugged lugs, and coupling grooves and rugged grooves formed on the distal end of the decoration tiles are coated with aerosol to form a coated layer to prevent the decoration tiles from being polluted with liquid foreign objects and to prevent the decoration tiles from being discolored and generating odor.

Abstract: The invention relates to a fabrication method of Ge—Mn magnetic semiconductor with a high Curie temperature. To date, most of researches in magnetic semiconductor are constrained to the magnetic semiconductors from group II-VI and group III-V. However, a new range of semiconductors from group IV has been recently added. Especially, Ge based semiconductors are attracting a significant attention. These magnetic semiconductors have very low Curie temperatures whose maximum is around 116 K. The low Curie temperature is a major stumbling block for commercial development. The exact reason for the low Curie temperature is not known, however, this is probably due to the low content of Mn. In order to resolve this problem, the present invention utilizes the thermal evaporation method to fabricate amorphous Ge—Mn alloys. As a result, a large amount of Mn is made solid soluble in Ge without any precipitation. Also, a relatively high Curie temperature of 250 K is obtained.
