Outline of Final Research Achievements

Magnetic recording has become high-density and miniaturization. According to this, the local detection technique of electromagnetic properties at nanoscale becomes extremely high demand. Researchers have spent much effort to detect the magnetic properties at nanoscale, which resulted in the development of several devices. For example, magnetic force microscope is a kind of scanning probe microscope, which detects the magnetic field of the sample surface using a magnetized probe. However, a quantitative measurement is sometimes difficult because the atomic force affects the detection results.
In this study, we demonstrated the spiral formation of the coated nanowire by self-deformation technique based on the residual stress of the thin film. The metal coated nanowire spirally formed with high conductivity. The electrical and magnetic properties of the coil was investigated. The coil is possible to be used as an electromagnet to detect the electromagnetic properties of nanomaterials.
