In this paper we give an overview of the magnetic and magneto-optical properties of Co/Pt and, to a less extent, Co/Pd multilayers as optimized for magneto-optical storage applications. The Co layers should be very thin, i.e. about 4 A , and the Pt l

The ferromagnetic resonance spectrum of a layered magnetic thin film is expected to show a number of standing spin‐wave resonances with a wavelength that matches the thickness of the film. For the case of perpendicular resonance such spectra were c

Domains written thermomagnetically under recording conditions in rare-earth transition-metal thin films are studied with Lorentz microscopy. A novel technique in which the magnetooptical layer is deposited on specially prepared silicon wafer disks pr

In this paper the sizes and shapes of thermally written magnetic domains in a GdTbFe layer are discussed. The magneto‐optical layer is deposited on a specially prepared silicon wafer disk, provided with Si3N4 windows. This allows dynamic writing of

Defect impurity levels have been examined in copper‐diffused p‐and n‐type silicon using deep level transient spectroscopy. Levels at Ev+0.09, Ev+0.23, and Ev+0.42 eV have been observed in both types of material, although the deeper levels were

We prepared by vapor deposition at room temperature thin (500 A) Co/Pt multilayers or layered structures directly onto glass or Si substrates. They show a preferential magnetization perpendicular to the film plane for Co thicknesses below 12 A and a

In magneto‐optic recording, the most direct way to overwrite stored information is to switch the magnetization in a laser‐heated region of the magneto‐optic layer by means of an alternating magnetic field generated by a magnetic head. The heat

In this letter we demonstrate thermomagnetic writing in a Co/Pt thin‐film layered structure or multilayer: 25×(4.1 A Co+19 A Pt). This film exhibits perpendicular magnetic anisotropy, 100% remanence, and a coercive field of 76 kA/m at room tempera
