    Modeling, simulation and design of magneto-optical multilayer thin film systems

    The simulation software MagOpS can be used to model the magneto-optical response of multilayer thin film systems with single (MagOpS SINGLE) or multiple (MagOpS MULTI) magnetizable magnetic thin films in a multilayer thin film system. For example, using MagOpS, the structure of multilayer thin film systems can be optimized for applications in magneto-optical sensorics or in optical data storage.

    Multiparameter optimization of magneto-optical response

    MagOpS stands for Magneto-Optical Simulation and is based on a user-friendly GUI. It is a versatile software for optimizing the design of a magneto-optical sensor and its operation (wavelength range l, angle of incidence AOI, polarization state of incident and reflected/transmitted light). Furthermore, the wavelength dependent magneto-optical coupling constant Q can be extracted. Currently, the software code runs best on Matlab 2016a platform and upgrades its compatibility to latest Matlab version.

    Complex dielectric tensor elements of each layer of the magnetic multilayer system: 3 nm Ru, 20 nm Permalloy (Py), 3 nm Ta, 1000 nm SiO2, 0.5 mm Si substrate in 300 nm to 1000 nm wavelength range. Saturation magnetization of Py amounts to 119 emu/g. Magnetooptical coupling constant Q of Py has been taken from the MagOpS database

    How does MagOpS work?

    The user defines a multilayer thin film structure with single (MagOpS SINGLE) or multiple (MagOpS MULTI) magnetizable magnetic thin films including thickness and optical constants of each layer and saturation magnetization and magneto-optical coupling constant Q of each magnetizable layer.

    The software calculates the magneto-optical response of multilayer thin film systems, e.g. the complex Kerr angle in dependence on the thickness of each layer, optical constants of each layer in dependence on the wavelength dependent magnetooptical constant of each magnetizable layer, the magnetic field dependent magnetization of each magnetizable layer and in dependence on its operation wavelength range, angle of incidence AOI, polarization state of incident and reflected/transmitted light.

    Benefits of MagOpS

    • User-friendly GUI
    • Works with spectral ellipsometry data in standard format
    • Number of layers in the multilayer stack depends on the licence model (MagOpS Single, MagOpS Multi)
    • Calculates the magneto-optical response (-of a multilayer thin film system) in dependence on its operation wavelength range, angle of incidence, polarization state of incident and reflected/transmitted light
    • Fits the complex magnetooptical dielectric tensor of magnetizable layers in a multilayer thin film system (MagOpS Service)

     

    There are currently 3 licence models available: Single, Multi and Service. Please use for your order the order form.
