Magnetic ceramic films containing metal-rich nanoworm reticulations 200–550 nm wide have been fabricated from a highly metallized metallopolymer resist (see Figure) using oxygen or hydrogen plasma reactive ion etching in a secondary magnetic field. Applications may be found in spintronics and logic circuits.
