| Research Abstract |
Low current driven "SPIN LOGIC" has been proposed. We have already succeeded to reduce current denssity for driving domain wall on TbFeCo magnetic wire. Using the TbFeCo magnetic wire, 2 input ports and 1 output port logic circuit was fabricated. When the width of output port is wider than that of input port, the logic works for "AND" operation. In case of nallow width of output port, it works for "OR" logic. These were successfully demonstrated. Moreover, "NOT" and "FUNPOUT" demonstrations were also succeeded. The spin logic circuit and memory can be integrated in the sama substrate and operateed with low current. Thus, current driven spin logic and memory is very attractive for "LOGIC in MOMORY".
