Nonlinear magneto‐optics is a very sensitive fingerprint of the electronic, magnetic, and atomic structure of surfaces, interfaces, and thin ferromagnetic films. Analyzing theoretically the nonlinear magneto‐optical Kerr effect for thin films of Fe(001) and at Fe surfaces we demonstrate exemplarily how various electronic material properties of ferromagnets, such as the d‐bandwidth, the magnetization, the substrate lattice constant, and the film‐thickness dependence can be extracted from the…

This electronic theory confirms the previous assertion that the nonlinear magneto-optical Kerr effect should be observable and clearly shows that this effect contains detailed information about the electronic and magnetic surface properties (band structure, exchange interaction, spin-orbit coupling).

It is shown that surface magnetization can induce a number of nonlinear susceptibility elements that would vanish otherwise and an order-of-magnitude estimate suggests that these induced elements are detectable by optical second-harmonic generation with appropriate polarization combinations.
Effects of surface magnetism on optical second harmonic generation.
The magneto-optical Kerr erect modifies the hyperpolarizability of the surface in the optical field, leading to a dependence of the second harmonic yield on the direction of magnetization relative to the light fields.
Interface magnetism and possible quantum well oscillations in ultrathin Co/Cu films observed by magnetization induced second harmonic generation.
Very strong oscillations in the MSHG signal are found for the Cu/Co/Cu system as a function of the thickness of the Cu coverlayer, which are possibly related to quantum well states in these thin Cu films.
