Research Abstract

Some of 4d/5d transition metals, e.g., Pd and Pt, have nearly ferromagnetic nature, and thus appearance of ferromagnetism is expected through increase in density of states at Fermi energy under a certain condition. When these materials have low-dimensional structures, especially, the magnetic change from nonmagnetic to ferromagnetic states can be manipulated through some extrinsic operation. Such a nonmagnetic to ferromagnetic switching can be used for the development of magnetic devices. In this study, the fundamentals of magnetic manipulation, which is based on the induction of ferromagnetism to satisfy Stoner's criteria by changing the density of states using electrical, optical and dynamical techniques, were investigated.
