Magnetooptic Effects and Possibility Their Application for Fiber Optic Sensor Technique

In the work some magnetooptic effects were presented. More detail the phenomenon of optical birefringence was discussed. Among magnetic effects one distinguishes Faraday's effect, in which the direction of external magnetic field and light wave ii parallel and Cotion-Mutton effect where the above directions are perpendicular. Very interesting, for the sensor applications, are also magnetostriction effects. In the paper the discussion on possibility of application in sensor technigue the various magnetosensing materials was curry out.
