| Research Abstract |
Higher recording density and higher speed recording are required for magnetic recording in information storage field, high density writing/reading and high speed writing techniques have been studied in the world. High speed reading technique will be a key issue for development of high speed recording techniques because of its physical limit of ferromagnetic resonance frequency. In this research, surface plasmon was investigated to be applied to magnetic sensing techniques for ultra揺igh reading sensor. Magnetic response of surface plasmon was observed in Co/Cu multilayer films, which films were composed by a surface plasmon generation layer and a controlling layer magnetically. Furthermore, Direction dependence of applied field on surface plasmon generation was observed.
