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...

We investigate the Kerr and magneto-optical effects for a probe laser field with two orthogonally polarized components, propagating in cold Rydberg atomic gas an inverted-Y-type level configuration via double electromagnetically induced transparency (EIT). Through approach beyond both mean-field ground-state approximations, we make detailed calculations on third-order nonlinear optical suscepti...

The authors have investigated the correlation between magnetic properties, growth structure, and internal stress of epitaxially grown Co35Pd65 alloy films on Cu–Si(100) in the alloy thickness range from 1 monolayer (ML) to 10 ML. An in situ surface magneto-optical Kerr effects (SMOKE) study revealed that Co35Pd65 alloy films showed room-temperature ferromagnetism at a coverage of 2 ML with a st...
