mrfmsim 0.4.2

mrfmsim is a Python framework for simulating magnetic resonance force microscopy (MRFM) experiments. The package is based on the mmodel framework, which provides modular modeling capabilities for the experiments.

This mrfmsim package contains tools to simulate signals in a Magnetic Resonance Force Microscope (MRFM) [1] [2] [3] experiment. The code in the package simulates signal from electron spins, particularly the nitroxide spin radical “TEMPO” to selected nuclear spins (1H, 19F, and 71Ga).

The package host variety of MRFM experiments with the tip-on-cantilever setup. It can simulate signals from both Curie-law spin magnetization and spin fluctuations (in the small polarization limit); and can simulate force experiments and force-gradient experiments (in the small-cantilever-amplitude limit and without the small amplitude approximation — in the large amplitude limit). It can simulate signal with the cantilever and field-aligned in both the hangdown [4] and SPAM [5] [6] experimental geometries.
