“…The pyrolysis method starting typically from a solution of metal nitrates [10,13,26] permits to produce a large variety of compositions and is only limited by the insolubility of certain metal salts. The metal concentration in the crystallized film is almost identical with that in the starting solution.…”

“…However, their long-term stability and figure of merit at shorter wavelengths are less satisfactory. The recently developed processes for thin film deposition of magnetic oxides such as pyrolysis [10][11][12][13] and magnetron sputtering [14][15][16] made the ferrimagnetic oxides again serious candidates for magneto-optical recording media [16][17][18][19]. They might overcome the mentioned deficiencies' of the rare-earth transitionmetal alloys but there are also some critical aspects associated with these polycrystalline thin films which concern primarily the uniaxial anisotropy, the coercivity, grain noise and the high crystallization temperatures.…”

-The present contribution reviews the current status of ferrirnagnetic oxides for magneto-optical recording where special attention is paid to iron garnet fi1.ms deposited by pyrolysis and sputtering. The magnetic and magneto-optical properties are discussed. The influence of the preparation conditions and the annealing treatments controlling microstructure, grain size and homogeneity of the films are analyzed with respect to their relevance to structure-sensitive quantities such as coercivity, noise and other recording parameters determining the performance of magneto-optical disks.

For the purpose of reducing the media noise Nn of garnet films for magneto-optical recording, we investigated the technique to increase the stress induced perpendicular uniaxial anisotropy energy KA, by stacking the garnet film with the stressed overlayer. KA, of the garnet film was increased from 1.4xl0 4 to 2.2xl04 erg/cm 3 by stacking with the stressed reflective Al-TI overlayer. This effect leads the decrease in N n and the increase in the carrier to noise ratio (CNR). As a consequence, CNR = 55-56 dB was achieved.
