About awarded research(activity)
Title: Spin-charge current conversion and magnetotransport phenomena in all-epitaxial spin-orbit ferromagnetic oxide heterostructures: In today's information society, the rapid increase in the amount of information has led to a continuous increase in the power consumption of information processing devices and memory. As a result, spintronics, which utilizes the spin of electrons (the property of electrons as magnets), is being actively pursued. In general, spintronic devices use the orientation of magnetization (NS direction) in ferromagnetic materials (magnets) to record information as "0" and "1", allowing information to be retained without power supply and greatly reducing power consumption. Recently, devices have been developed that focus on the interconversion phenomenon between spin current, the flow of electron spins, and electric current, the flow of electron charges. It is believed that the higher efficiency of this "spin-charge current interconversion" leads to the lower power consumption for device operation. In this study, we have successfully achieved the most efficient spin-charge current conversion using a two-dimensional electron gas formed at the LaTiO3+δ/SrTiO3 interface. Furthermore, through theoretical calculations, we have provided guidelines for material design to achieve high conversion efficiency. In addition, we have explored ferromagnetic materials and novel physical phenomena for the realization of ultra-low power memory.
