Magnetic Recording: Magnetic‐Pole Flip by Millimeter Wave (Adv. Mater. 48/2020)
In article number 2004897, Shin‐ichi Ohkoshi and co‐workers propose a new magnetic recording methodology, “focused‐millimeter‐wave‐assisted magnetic recording (F‐MIMR)”, to drastically increase the recording density of magnetic tapes. Demonstrations are performed using magnetic films based on a seri...

| description | In article number 2004897, Shin‐ichi Ohkoshi and co‐workers propose a new magnetic recording methodology, “focused‐millimeter‐wave‐assisted magnetic recording (F‐MIMR)”, to drastically increase the recording density of magnetic tapes. Demonstrations are performed using magnetic films based on a series of epsilon iron oxide, ε‐Fe2O3. Irradiation of the focused millimeter wave generated from terahertz (THz) light flips the magnetic pole direction, leading to a breakthrough technology for high‐density magnetic recordings. |
