Direct observation of the energy band gaps for surface-plasma waves propagating through corrugated dielectric-structure on a flat metal surface

We demonstrated first to our knowledge that the surface plasmon polaritions(SPP) band gap can be observed directly from corrugated dielectric structures on a flat metal surface.
The picture shown left is a SPP dipersion curves revealing the SPP band gap(2.038x10¹⁴/s) near the red color region, and right-hand side the dispersion curves calculated by using two different methods of plane wave expansion (solid curves) and rigorus coupled wave analysis (small boxes), confirm the experimental result to its theory.

Enhanced magnetic and spin-photonic properties using metastable quantum structure

When atoms form a solid state, most of the atoms lose their magnetic property. Even for the ferromagnetic materials in solid state, their magnetic moments are far less than their maximum possible values in the atomic state. Usually the magnetic moments in the solid state are about a half of the corresponding atomic values. Many efforts have been devoted to increase in the magnetic moments of those materials in various solid states, such as alloys, thin films, interfaces, multilayers, and so on. They were not successful. We realized a large magnetic moment close to atomic value by creating some special state, the so-called metastable state, through magnetic ion- beam mixing(MIBM) in the bulk phase. This ferromagnetic moment can play an important role as a promising candidate in sciences and focused on stable alloys and crystalline multilayers so far.
