Nature of problem:
Numerous problems of ferromagnetic nanoelements can be investigated with micromagnetic simulations using The Object Oriented MicroMagnetic Framework (OOMMF). Often, research requires continuous parameters and condition changes while running a large number of simulations with time-varying parameters, which means that the user has to be experienced with programming and that a lot of time has to be spent on creating numerous expanded Mifs. What is more, after the simulations are finished, the analysis of a large number of resultant files often turns out to be a rigorous and relatively time-consuming process. Additionally, even though OOMMF is being continuously extended, gaining possibilities of simulating new phenomena, such extensions tend to suffer from drawbacks of open source paradigm, i.e. lack of documentation and highly specific interfaces.

Solution method:
MAGE provides an easy-to-use graphical user interface (GUI) that overcomes all programming barriers for fast and error-free development of highly complicated systems and external time-varying conditions. The program contains tools allowing for modelling of the most recent phenomena such as spin-transfer-torque, voltage-induced anisotropy changes and magnetoresistance calculations as well as a possibility of registering local magnetization changes. We provide a convenient GUI for fast, efficient and automated data analysis, including both classical Fourier analysis as well as more advanced wavelet approach.

Running time:
Negligible for configuration and data-process files creation. For evaluation of generated scripts strongly depends on sample size and time span being investigated, but should not exceed several minutes in a typical case.
