We are doing theoretical research on electrical conductivity in magnetoresistive devices using highly spin-polarized materials. The aim is to achieve very functional spintronics devices such as read-out heads for ultrahigh-density magnetic recording and non-volatile spin memories. We also investigate magnetoresistive devices using perpendicularly magnetized materials to ensure endurance against thermal fluctuations of the magnetization. We successfully achieve a guideline for improvement of the magnetoresistive performance by designing the crystal structure at the interface between ferromagnets and oxides theoretically.
We believe that first-principles calculations, which need no empirical parameter, play a very important role in research and development of various materials. Please contact us if you want to collaborate with us.
