Longitudinal Magneto-Optical Kerr Effect in Ce:YIG Thin Films Incorporating Gold Nanoparticles

We report an experimental study on optical and magneto-optical properties of Cesubstituted yttrium iron garnet thin films incorporating gold nanoparticles. Au nanoparticles were formed by heating Au thin film on cubic quartz and garnet substrate in vacuum chamber and a Ce:YIG layer was deposited on them by the aid of Pulsed laser deposition method. A large enhancement of the longitudinal Kerr e...

Giant 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,...

Large area magneto-optical investigations of YBCO thin films

A new apparatus for magneto-optical investigations of high temperature superconducting ~HTS! films as large as 20320 cm is presented. With this equipment flux penetration of an external magnetic field into YBCO thin films has been studied by scanning the samples through an inhomogeneous magnetic field ~magneto-optical scanning technique, MOST!. The normal penetration of magnetic flux into a sup...

MAGNETO-OPTICAL KERR EFFECTS OF AMORPHOUS Nd-Co FILMS

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.
