| Abstract(in English) | Magnetic tunnel junctions (MTJs) with highly oriented (001) MgO barrier/CoFeB ferromagnetic electrodes have attracted much interest because of the application to eco-friendly spin devices such as magnetoresisitive random access memories and nonvolatile logics with low-power consumption. We here describe giant tunnel magnetoresistance (TMR) ratio at room temperature (RT) and current-induced magnetization switching (CIMS) at relatively low critical current density J_C for the MgO barrier MTJs. |
