  Article:   MAGNETO-OPTICAL MICROSCOPY AND ITS APPLICATION.

Authors:  RUDOLF SCHÄFER.
 
       
         
  Abstract:  The magnetic microstucture, i.e. the arrangement of domains and domain walls, forms the mesoscopic link between basic physical properties of a magnetic material and its macroscopic properties. Hysteresis phenomena, energy loss in inductive devises, noise in sensors, or the magnetoresistive properties of modern spintronic devices are decisively determined by the peculiarities of the underlying magnetic microstructure, especially by irreversibilities in the magnetization process. The development and optimization of magnetic materials therefore requires a solid knowledge of the underlying domains and their reaction to magnetic fields. In most cases, such knowledge can only be gleaned by direct imaging.
