Influence of Nuclear Tracks on the Coercitivity of Single Crystalline (Gd,Bi)3(Fe,Ga)5O12 LPE Garnet Films; H. Heitmannn, P. Hansen, K. Witter, R. Spohr; J. Magnetism and Magnetic Materials, vol. 10, pp. 97 - 99, (1979)

The domain wall coercivity in single-crystalline liquid-phase epitaxial (LPE) garnet f'flms is much too low for high-density information storage application. The defect density has to be increased by toughly 5 orders of magnitude to achieve storage densities of up 10^6 bit/cm 2. A sensitive control of the coercivity can be attained with nuclear tracks from high-energy (1.4 MeV/nucleon) Xe or U ions with densities ranging from 10^7 to 10^l0 cm^-2.
