After a one year stay as a postdoctoral associate at Kyoto University\, he move d to Keio University where he became an assistant professor. In 2000\, he moved to Osaka University where he became a lecturer and an associate prof essor. Since 2004\, he has been working at Kyoto University\, where he is now a professor. He has published over 280 technical articles in peer-revi ewed journals\, including book chapters and review articles\, and has give n more than 90 invited presentations at international conferences. He serv ed as conference co-chair of the 8th International Symposium on Metallic M ultilayers (MML) in 2013\, and on the program committees of various intern ational conferences on magnetism and spintronics.\n\nAbstract\n\nWe found the superconducting diode effect (SDE) in Nb/V/Ta superlattices with a pol ar structure\, which is the ultimate\n\ndiode effect exhibiting a supercon ducting state in one direction and a normal state in the other [1-3]. The SDE can be\n\nconsidered as the nonreciprocity of the critical current for the metal-superconductor transition. We have also found the\n\nreverse ef fect\, i.e.\, the nonreciprocal critical magnetic field under the applicat ion of supercurrent [4]. We also found that\n\nthe polarity of the superco nducting diode shows a sign reversal when the magnetic field is increased [5]. Recently\, we\n\nhave succeeded in demonstrating zero-field SDE by in troducing ferromagnetic layers into superlattices [8\, 9]. The polarity\n\ nof the SDE is controlled by the magnetization direction of the ferromagne tic layer\, leading to the development of novel\n\nnon-volatile memories a nd logic circuits with ultra-low power consumption.\n\nThis work was partl y supported by JSPS KAKENHI Grant Numbers (18H04225\, 18H01178\, 18H05227\ , 20H05665\,\n\n20H05159\, 21K18145)\, MEXT Initiative to Establish Next-g eneration Novel Integrated Circuits Centers (X-NICS) Grant\n\nNumber JPJ01 1438\, the Cooperative Research Project Program of the Research Institute of Electrical Communication\,\n\nTohoku University\, and the Collaborative Research Program of the Institute for Chemical Research\, Kyoto Universit y.\n\nReferences\n\n[1] F.
