Magnetooptical thin film reading head

Applied Optics, 1986
A new type of magnetooptical reading head is studied, in which the output signal is magnetooptically produced from the head pole edge vertically positioned on the magnetic recording media. The calculations suggest that this reading head, which has a reproducibility of more than 3000-bits/mm recording density, is realizable.

Magnetooptical current transformer 2: Components

Applied Optics, 1980
In this second part, the most important components of a magnetooptical current transformer are described and their suitability is discussed. Today He-Ne gas lasers and laser diodes seem to meet best the requirements of the light source. Single-mode optical fibers are capable of transmitting polarized light without depolarization.

Noise sources in magnetooptic recording

Applied Optics, 1988
This paper investigates nonwhite noise sources important in magnetooptic recording. These noise sources are experimentally characterized, and their contribution is quantified across a 20-MHz bandwidth.

Nonreciprocal Magnetooptic Waveguides

IEEE Transactions on Microwave Theory and Techniques, 1975
The longitudinal magnetooptic effect can be used in a unique way to mix TE and TM modes of a planar dielectric waveguide where the strength of mixing is dependent upon propagation direction (forwards or reverse). A detailed study of Faraday effect circulators in optical dielectric waveguides is presented and accurate design data for a practical version

Two photon magnetooptic effects

Physics Letters A, 1977
Abstract The theory of two photon magnetooptic effects such as polarization rotation and circular dichroism is developed. An effect which has not been previously discussed, the optical analog of the Hanle effect, is proposed.

Magnetooptical studies of metamagnets

AIP Conference Proceedings, 1975
Techniques based on magnetooptical rotation have recently been of great use in the study of metamagnetic crystals. Under achievable conditions this rotation is a measure of M which may be measured automatically as H or T vary. The distinctly different rotations of coexisting anti‐ and paramagnetic phases at the first order metamagnetic transition make ...

A Brief Survey of Magnetooptics

Applied Optics, 1967
A brief account is given of many of the areas being studied by magnetooptic techniques today. The main effort is in solids with the spectrum being broadly covered from the uv to the rf region.
