The MO microscope can be used to study ferromagnetic materials with both perpendicular-to-plane and in-plane magnetic anisotropy via polar Kerr and Voigt effects, respectively. The functionality of the Voigt effect-based microscope was tested using an in-plane magnetized ferromagnetic semiconductor (Ga,Mn)As. It was revealed that the presence of mechanical defects in the (Ga,Mn)As epilayer alters significantly the magnetic anisotropy in their proximity. The importance of MO experiments with simultaneous temporal and spatial resolutions was demonstrated using a (Ga,Mn)As sample attached to a piezoelectric transducer, which produces a voltage-controlled strain. We observed a considerably different behavior in different parts of the sample that enabled us to identify sample parts where the epilayer magnetic anisotropy was significantly modified by the presence of the piezoelectric transducer and where it was not. Finally, we discuss the possible applicability of our experimental setup for the research of compensated antiferromagnets, where only MO effects even in magnetic moments are present.","11 S.","http://dx.doi.org/10.17169/refubium-820","https://refubium.fu-berlin.de/handle/fub188/23022","eng","http://www.fu-berlin.de/sites/refubium/rechtliches/Nutzungsbedingungen","500 Naturwissenschaften und Mathematik::530 Physik::530 Physik","magneto-optical microscope","Voigt effect-based wide-field magneto-optical microscope integrated in a pump-probe experimental setup","Wissenschaftlicher Artikel","open access","073703","10.1063/1.5023183","Review of Scientific Instruments","7","https://doi.org/10.1063/1.5023183","89","Physik","Open Access Publikation in Allianzlizenz","no"
