Magnetization-induced optical second-harmonic generation from magnetic multilayers

Interface Magnetism and Possible Quantum Well Oscillations in Ultrathin Co/Cu Films Observed by Magnetization Induced Second Harmonic Generation

“…Our calculation is based on a multiple reflection model, including nonlinear sources at the interfaces. Details of the method are published in a separate publication [20]. In brief, using the relevant ten sor elements and the boundary conditions for a nonlinear source polarization at an interface, the discontinuity of the SH field at the interface is derived.…”

“…Assuming a bulklike electronic structure of the Cu films, the Cu thickness dependence of p(pp) can be calculated from our multiple reflection model [20] using the values of the various tensor elements as derived from our experiments. The dashed line in Fig.…”

Magnetization-induced second-harmonic generation of light by exchange-coupled magnetic layers

“…24,25 To be consistent with our previous research we prefer to analyze our MSHG data by using the electric point dipole model. 24 The present analysis does not consider higherorder terms in the expression of the dipole moment, such as that which is quadratic in magnetization, or magnetization gradients.…”

Nonlinear Magneto-Optics:a Novel Probe for Magnetic Interfaces

“…A crucial challenge for the applicatioll of MSIIC for multilayer syst.ems is how t.o derive the non linear tensor X(2) from the experimental data. We use multiple scattering calculations (based on a transfer matrix technique [12,13]) to determine the electric field E(w) for every interface; the same calculation procedure is used afterwards to compute the outgoing SHG intensity. The tensor components \;2) for every interface i serve as fitting parameters to describe the experimental data.…”
