Impact of Magneto-optical Properties Depending on the Orientation in the Plane of Cobalt Ferrite Locked in a Silica Matrix

Nandiguim Lamai, Désiré Allassem, Alexis Mouangué Nanimina, Djimako Bongo & Togdjim Jonas · Asian Journal of Physical and Chemical Sciences · 2021

In this work, we discuss the magneto-optical properties according to the orientation of 15nm-sized cobalt ferrite blocked in a silica matrix in comparison to the study done on 20nm-sized cobalt ferrite. This measurement shows that it is possible to increase the remanence of the F...
