Journal ArticleDOI
Determination of the Magnetic Symmetry of Hexagonal Manganites by Second Harmonic Generation
Manfred Fiebig,Dietmar Fröhlich,Kay Kohn,S. Leute,Thomas Lottermoser,Victor V. Pavlov,Roman V. Pisarev +6 more
TL;DR: Optical second harmonic spectroscopy is introduced as a powerful supplement for the determination of complex magnetic structures and some earlier conclusions on their magnetic symmetry and properties should be revised.
Journal ArticleDOI
Charge transfer transitions in multiferroic BiFeO3 and related ferrite insulators
Roman V. Pisarev,A. S. Moskvin,Alexandra M. Kalashnikova,Alexandra M. Kalashnikova,T.H.M. Rasing +4 more
TL;DR: In this paper, the optical response of multiferroic (BiFeO) and related complex iron oxides was studied in the wide spectral range from 0.6 up to 5.8 eV using spectroscopic ellipsometry.
Journal ArticleDOI
Second harmonic generation and magnetic-dipole-electric-dipole interference in antiferromagnetic Cr2O3.
TL;DR: This paper presents a novel tool to study antiferromagnetic domains with opposite orientation of the order parameter, which leads to a pronounced polarization dependence for circularly polarized light propagating along the optical axis.
Journal ArticleDOI
Ultrafast optical modification of exchange interactions in iron oxides
Rostislav Mikhaylovskiy,Rostislav Mikhaylovskiy,Euan Hendry,Andrea Secchi,J.H. Mentink,Martin Eckstein,Aiping Wu,Roman V. Pisarev,V. V. Kruglyak,Mikhail I. Katsnelson,Theo Rasing,Alexey Kimel +11 more
TL;DR: This work proposes a scenario for coupling between the electric field of light and spins via optical modification of the exchange interaction and demonstrates that this isotropic opto-magnetic effect, which can be called inverse magneto-refraction, is allowed in a material of any symmetry.
Journal ArticleDOI
Laser-induced ultrafast spin dynamics in ErFeO 3
TL;DR: In this article, the authors used 100-fs optical laser pulses to excite and probe spin dynamics in the rare-earth orthoferrite (ErFeO)) in a broad temperature range with the focus on the vicinities of the compensation point.
