TLDR
In this article, the authors proposed a multileyer structure for magneto-optical information storage in thin films of amorphous rare-earth transition-metal alloys, where the information is stored via magnetic domains, which can be written by a thermomagnetic switching process.About:

Magnetic and magneto‐optical properties of rare‐earth transition‐metal alloys containing Dy, Ho, Fe, Co
TL;DR: In this paper, the saturation magnetization, uniaxial anisotropy, coercivity, and Faraday rotation were investigated as a function of composition and temperature, and the magnetization data indicate a strong dispersion of the RE moments due to randomly oriented local crystal field axes.

Magnetically coded device
TL;DR: In this paper, nonmagnetized permanent magnet material is heated in a pattern by a laser beam to a localized temperature above the Curie point or a temperature sufficient to reduce the coercivity sufficiently for an external field to magnetize the pattern in the direction of the field.

TL;DR: In this paper, a linear Halbach array was fabricated to demonstrate the potential of TMP for the realization of complex multidirectional microflux sources, and a simple model provided semiquantitative agreement with the experimental results.

Crystallization Behaviour and Magnetic Properties of Magnetostrictive TbDyFe Films
TL;DR: Amorphous magnetostrictive films of the composition (Tb 0.27 Dy 0.73 ) 0.3 Fe 0.7 have been prepared by ion-beam sputtering as discussed by the authors.

Chapter 3 Magneto-optical kerr spectra
TL;DR: The theoretical explanation of magneto-optical Kerr effect (MOKE) spectra was at that time in its infancy, and consequently all the insight that theory could give in the microscopic mechanism leading to large Kerr rotations was mainly speculative, because nothing could be proven by first-principles calculations.

Magneto-optical recording characteristics of TbFeCo media by magnetic field modulation method
TL;DR: In this paper, the authors investigated the static and dynamic recording characteristics of a TbFeCo film relative to an external magnetic field and determined that a medium with a compensation temperature between room temperature and about 100°C is suitable for magnetic field modulation recording.

Single ion model for perpendicular magnetic anisotropy in RE-TM amorphous films
TL;DR: In this article, the authors investigated the mechanism of perpendicular magnetic anisotropy in rare earth transition metal amorphous films, and proposed a model in which anelastic deformation during deposition of the film is responsible for the induction of K u.
