Abstract: A magnetic device includes a pinned layer having a fixed magnetization direction, a free layer having a switched magnetization direction, a tunnel insulating layer interposed between the pinned layer and the free layer, and a spin-torque generation layer injecting spin current into the free layer as in-plane current flows. The spin current allows a magnetization direction of the free layer to be switched by a spin-orbit torque. The pinned layer and the free layer have perpendicular magnetic anisotropy. The spin-torque generation layer includes a tungsten layer and a tungsten-nitride layer sequentially stacked. The tungsten-nitride layer is disposed adjacent to the free layer.

Abstract: The present invention relates to a composition for target substance detection using a magnetic nanoparticle having a Curie temperature which is within a biocompatible temperature range, a target substance detection system, and a method for obtaining an image of a living body or specimen. As the magnetic nanoparticle of the present invention has a Curie temperature within the temperature range of 0° C. to 41° C., the ferromagnetic and paramagnetic properties of the magnetic nanoparticle may be controlled within a biocompatible temperature range at a temperature at which a biological control agent is not destroyed, and the temperature of the magnetic nanoparticle is adjusted to control the magnetic properties thereof such that the properties of the magnetic nanoparticle may be used only when ferromagnetic properties are required, such as in the case of signal amplification in detecting, separating, and delivering biological control agents. Accordingly, the present invention can provide a biological substance detection system which satisfies both a decrease in non-specific binding and signal amplification using a magnetic nanoparticle having a Curie temperature which is within a biocompatible temperature range, and can be reused after detection.

Abstract: Disclosed herein is a technique for synthesizing chiral magnetic nanocoils using an electrodeposition technique, which can be used to fabricate magnetic nanosensors capable of generating an electric field by strongly reacting to an external magnetic field, such as Faraday's law of electromagnetic induction at the nanoscale, depending on the coil shape of the nanostructure. In accordance with one embodiment, a method of synthesizing a chiral magnetic nanocoil may include generating a primary particle composed of metal ions by applying an external electric field, binding a chiral molecule to a surface of the generated primary particle, and controlling an assembly direction of a next primary particle by the bound chiral molecule.
