Outline of Final Research Achievements

Current driven domain wall memory with RE-TM magnetic layer has been investigated. Generally, FeNi or Co/Nimagnetic wires have been fabricated by etching process. However, it gives a damage to the magnetic wire edge, then it will interfare with the domain wall motion. Threfore, a new magnetic wire fabrication technique without etching has been proposed. It is named as nano-imprinted magnetic wire. By using this technique, we have succeded to obtain smooth wire edge and the critical current density of domain wall motion has been drastically improved compared with that of the conventional magnetic wire as FeNi alloy and Co/Nimultilayer. By using the nanoimprint RE-TM magnetic wire fabrication technique without any etching process, 45nm width magnetic tire with smoothe edge has been fabricated successfully. Next, a recording mark was fabricated on the narrow track by commercialized magnetic head. The recorded mark has been also obsereved by sccaning image of the TMR head.
