Determination of the infrared complex magneto-conductivity tensor in itinerant ferromagnets from Faraday and Kerr measurements
نویسندگان
چکیده
We present measurement and analysis techniques that allow the complex magneto-conductivity tensor to be determined from measurements of the complex Faraday (θF) and Kerr (θK) angles. θF and θK are measured in a Ga1−xMnxAs and SrRuO3 films. Thick film transmission and reflection equations are used to convert the complex θF and θK into the complex longitudinal conductivity σxx and the complex transverse (Hall) conductivity σxy. The resulting σxx is compared to the values obtained from conventional transmittance and reflectance measurements, as well as the results from Kramers-Kronig analysis of reflectance measurements on similar films.

Having precise hysterics loop of thin ferroelectric and ferromagnetic layers for optical switching and optical storages are important. A hysterieses loop can be achieved from a phenomenon call the magneto-optic effect. The magneto-optic effect is the rotation of a linear polarized electromagnetic wave propagated through a ferromagnetic medium. When light is transmitted through a layer of magnet...
متن کاملGiant magneto-optical Kerr effect and universal Faraday effect in thin-film topological insulators.
Topological insulators can exhibit strong magneto-electric effects when their time-reversal symmetry is broken. In this Letter we consider the magneto-optical Kerr and Faraday effects of a topological insulator thin film weakly exchange coupled to a ferromagnet. We find that its Faraday rotation has a universal value at low frequencies θF=tan(-1)α, where α is the vacuum fine structure constant,...

The complex off-diagonal components of conductivity tensor (g:, = 4, + i<,) of Co, a-Nd-Co and a-Y-Co was obtained by measuring magneto-optical Kerr effects, reflectivity and transmissivity in the range of fw = 0.8 eV 5eV. Nd-Co showed much greater wcr;, than Y-Co and the difference was deduced to be due to 4f T--t 5d 1. electron transition of Nd.
متن کاملUltrafast demagnetization in Ni: theory of magneto-optics for non-equilibrium electron distributions
The sensitivity of the magneto-optical Kerr response to electronic thermalization processes in ultrafast pump–probe experiments is studied by evaluating the complex conductivity tensor of Ni for non-equilibrium electron distributions. The electronic structure and optical matrix elements are calculated within density functional theory. To account for the electronic redistributions generated by t...
