Magnetic domain structure and spin reorientation process
-
Yurij G. Pastushenkov
Abstract
The domain structure was investigated in the spin reorientation region on the (100) and (001) planes of Nd2Fe14B and R(Fe, Co)11Ti (R = Tb, Dy) single crystals by means of the magnetooptical Kerr effect. The magnetic phase diagram of a tetragonal magnetic crystal was theoretically calculated and the effect of domain structures on phase transitions is investigated. On the basis of the observed domain configurations and domain wall density calculations, possible models for the volume magnetization distributions in tetragonal magnetic crystals with “easy cone” and “easy plane” anisotropy have been discussed.
Abstract
Die magnetischen Domänenstrukturen in der (100)- und (001)-Ebene von Nd2Fe14B- und R(Fe,Co)11Ti (R = Tb, Dy)-Einkristallen wurden mit Hilfe des magnetooptischen Kerr-Effektes im Temperaturbereich des Spin-Reorientierüngsübergangs untersucht. Das magnetische Phasen-diagramm des tetragonalen magnetischen Kristalls wurde berechnet. Außerdem wurde die Wirkung der Domänenstrukturen auf die magnetischen Phasenübergänge analysiert. Anhand der beobachteten Domänenkonfigurationen und der Berechnungen wurden Modelle für die Magnetisierungsverteilung in tetragonalen magnetischen Proben entwickelt und diskutiert.
