Magnetic Domain Transition of Clustered Soft Magnetic Narrow Strips Caused by a Magnetic Small Particle

A unique functionality was reported for a thin film soft magnetic strip having a certain angle of inclined magnetic anisotropy. It can switch magnetic domain by applying surface normal field with a certain distribution. The domain switches between single domain and multi-domain. Our previous study s...

Description
Summary:A unique functionality was reported for a thin film soft magnetic strip having a certain angle of inclined magnetic anisotropy. It can switch magnetic domain by applying surface normal field with a certain distribution. The domain switches between single domain and multi-domain. Our previous study shows that this phenomenon appears not only a single element but also a case of adjacent configuration of the multiple narrow strips. In this paper, an appearance of magnetic domain transition is reported, when a magnetic particle is placed just above the magnetic strip element. This phenomenon is a candidate of a sensor with memory function, which can detect an existence of magnetic particle on a certain element of the clustered micro-strips.
