Optics Letters, 2013 We present an electrodynamical model of a novel quantum plasmonic device - magneto-optical spaser. It is shown that a spherical gain nanoparticle coated with a metallic magneto-optical shell can operate as a spaser amplifying circularly polarized surface plasmons.

Magneto-optical cooling of atoms [PDF]
Optics Letters, 2014 We propose an alternative method to laser cooling. Our approach utilizes the extreme brightness of a supersonic atomic beam, and the adiabatic atomic coilgun to slow atoms in the beam or to bring them to rest. We show how internal-state optical pumping and stimulated optical transitions, combined with magnetic forces can be used to cool the ...

Magneto-optical spectrum analyzer [PDF]
Review of Scientific Instruments, 2014 We present a method for the investigation of gigahertz magnetization dynamics of single magnetic nano elements. By combining a frequency domain approach with a micro focus Kerr effect detection, a high sensitivity to magnetization dynamics with submicron spatial resolution is achieved. It allows spectra of single nanostructures to be recorded.

The 2022 magneto-optics roadmap [PDF]
Journal of Physics D: Applied Physics, 2022 Abstract Magneto-optical (MO) effects, viz. magnetically induced changes in light intensity or polarization upon reflection from or transmission through a magnetic sample, were discovered over a century and a half ago. Initially they played a crucially relevant role in unveiling the fundamentals of electromagnetism and quantum mechanics.

Surface profile-tailored magneto-optics in magnetoplasmonic crystals
APL Photonics, 2022 The control of transverse magneto-optical Kerr effect (TMOKE) enhancement is realized by balancing the radiative and absorption losses in one-dimensional all-nickel magnetoplasmonic crystals.

MAGNETO-OPTICS OF ANTIFERROMAGNETS
Journal of the Magnetics Society of Japan, 1987 Abstract Antiferromagnetic crystals in which crystallographic sites occupied by magnetic ions from various sublattices are not transnationally equivalent and are not associated with each other by a symmetry center can have magneto-optic properties distinct from the properties of other antiferromagnets.

Study of Light Polarization by Ferrofluid Film Using Jones Calculus
Condensed Matter, 2022 We studied the polarized light patterns obtained using a thin film of ferrofluid subjected to an applied magnetic field. We obtained patterns of polarized light with magnetic field configurations between parallel plates, monopolar, tetrapolar, and ...
