Changelog

1.5.5

  • Extended the Stack models allowing for non-symmetric coupling between devices.
  • Stack current drivers can now be of any type are adequately scaled.
  • Custom definition of the ScalarDriver is now possible and documented.

1.5.0-1.5.4

  • Dipole interaction added to the SB Model
  • Kasdin 1/f noise generator added to the noise module and to the solvers
  • Reworking the solvers for better performance and stability
  • Added a simple noise model to the utils class. It exists outside standard simulation procedures.
  • Added LLGB bindings and code. The solver is still WIP and doesn't integrate with more advanced features yet.
  • Added aliases for ScalarDriver -- for example, instead of calling ScalarDriver.getConstantDriver, you can now call constantDriver directly to create a constant driver.
  • Improve stub detection across editors and IDEs

1.4.1

  • Adding a basic optimisation script in the optimization module.
  • Streamlit optimization updates.

1.4.0

  • Adding new, dynamic symbolic model compatible with Solver class. It is now possible to use the Solver class with LayerDynamic to solve the LLG equation.
  • Added tests for procedures and operators.
  • Added missing operators for CVector class in Python.
  • CVector is now subscriptable.
  • Added new CVector and AxialDriver initialisations.
  • VSD and PIMM procedures accept additional new parameters.
  • Added some optimization utilities like coordinate_descent.
  • Added a streamlit service for an example PIMM simulation.

1.3.2

  • Added new ScalarDrivers -- Gaussian impulse and Gaussian step.

1.3.1

  • CVector got extra functionality in Python bindings. Operators are now supported.
  • Domain Wall dynamics is now also for 2 layer systems. Added edge potential.
  • SB model generalised for N layers.

1.3.0

  • Adding DW dynamics 1D model with dynamic drivers. (Numba optimised)
  • Adding SB model for energy-based FMR computation. Gradient computed using Adam optimiser.
  • Moving resistance functions from utils to resistance
  • Introducing docs updates for tutorial notebook (dark/light toggle works now).
  • Reservoir computing is now exposed in Python in the reservoir computing module.

1.2.0

  • Oersted field computation helper class in cmtj/models/oersted.py. Basic functionality is there, but needs to be further tested and documented. Next release potentially will move the computation to C++ for speed.
  • Added Heun (2nd order) solver and made it default for thermal computation. This is a more stable solver than the Euler solver, but is slower. The Euler solver is still available as an option.
  • Stack class now supports arbitrary layer ids to be coupled.
  • Extended the plotting capabilities of the Stack class. Now supports plotting of the magnetic field and the current density.
  • Added alternative STT formulation which in some cases may be useful.
  • Fixed some minor bugs in the thermal solver.
  • Fixed some minor bugs in the Stack class.
  • Updating tutorials on the docs page.
  • Bunch of extra documentation and examples.
