Experimental results of photogalvanomagnetic effect (PGME), magnetoelectric interaction, and remanent photomagnetization in Mn containing ferrites during multiple photomagnetization (PM) are presented. It is established that the irreversibility is inherent in the phenomena related to PM, if PM is carried out at room temperature by illuminating the ferrites with linearly polarized laser beam under dc magnetic field. Possible mechanisms of resonance interaction during PGME and photomagnetization of ferrites are considered. [Russian Text Ignored].

In GaP, InP, and Si single crystals the annealing and fluence dependent concentration of defects produced by irradiation with fast neutrons and protons are studied by means of the positron annihilation technique (measurements of the positron lifetime and of the Doppler broadening lineshape of annihilation photons) and of internal friction measurements. In proton bombarded GaP a two stage annealing process is observed (stage I near 200° C and stage II near 600° C) and attributed to the annealing of point-like and extended defects, respectively. In neutron irradiated GaP all positron sensitive radiation defects disappear after annealing at 700° C. It is shown (i) that in all materials the positron lifetime and S-parameter increase with rising proton and neutron fluence and (ii) that elemental semiconductors exhibit stronger increases than compound semiconductors. An GaP-, InP- und Si-Einkristallen werden das Ausheilverhalten und die dosisabhangige Konzentration der durch Beschus mit schnellen Neutronen und Protonen erzeugten Defekte mittels der Methode der Positronenannihilation (Messungen der Positronenlebensdauer und der Dopplerverbreiterung der Spektrallinie der Annihilationsquanten) und der Methode der inneren Reibung untersucht. An protonenbestrahltem GaP ist ein zweistufiger Ausheilprozes zu beobachten (Stufe I bei 200° C und Stufe II bei 600° C). Die untere Stufe wird mit der Ausheilung punktartiger Defekte und die obere Stufe mit der Ausheilung ausgedehnter Defekte in Verbindung gebracht. In neutronenbestrahltem GaP verschwinden alle positronenempfindlichen Defekte nach Ausheilung bei 700° C. Es wird gezeigt, (i) das die Positronenlebensdauer und der S-Parameter bei allen untersuchten Materialien mit wachsendem Protonen- und Neutronenflus ansteigen und (ii) das bei Elementhalbleitern starkere Veranderungen auftreten als bei Verbindungshalbleitern.

A numerical method is given and discussed for some micromagnetic problems. The magnetic behaviour of geometric and magnetic rotationally symmetric particles is investigated here, especially the behaviour of finite cylinders. The numerical method bases on the minimization of the free energy. The minimum problem is transformed into a numerical convenient form by a discretization. The results about the magnetic behaviour of the finite cylinder differ from the known results of the infinite cylinder, especially the nucleation field is essentially reduced. The method and its possibilities are presented in this paper. Eine numerische Methode fur einige mikromagnetische Aufgabenstellungen wird vorgestellt und diskutiert.
