Simulation Software MagOpS - HZDR Innovation

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.

 Modelled magneto-optical response (16 elements of the 4x4 Mueller matrix) of a magnetic multilayer system in a magnetic field H = (Hx, Hy, Hz) = (0, 0, +0.4 T) and in the wavelength range from 300 nm to 1000 nm at an angle of incidence AOI = 45° in reflection mode.

Benefits of MagOpS

User-friendly GUI
