Visualizing magnetization at a particular time-step

[DebanjanPolley]

Hi, I am driving a system for 1000 ps with the following code:

T = 1000e-12
N = 1000
system.dynamics = mm.Precession(gamma0=gamma0) + mm.Damping(alpha=alpha)
td = oc.TimeDriver()
td.drive(system, t=T, n=N)

Then I need to plot the z component of magnetization (Mz) of the system and I am doing it in the following way:

import matplotlib.pyplot as plt
fig, ax = plt.subplots(figsize=(20, 5))
system.m.plane('z', n=(20, 20)).mpl_vector(ax=ax)

Now, after the end of the simulation, is there a simple way to visualize Mz at some intermediate time-step: let's say T = 250, 500 and 750 ps?

Got it using some help from these two links.

Thank you for providing the links that help answer the question. This is really useful to build up a knowledge data base here, and will help other users as well.

Why I can not open the link you shared about visualization? I mean this : https://github.com/ubermag/workshop/blob/master/tutorials/mpl-visualisation.ipynb it shows : 404 : page not found. from where I can see the context of this link?

Hi @Milad-spinwave, the documentation has been re-organised a while ago. Please refer to this page for visualisation with matplotlib: https://ubermag.github.io/documentation/notebooks/discretisedfield/field-matplotlib-visualisation.html

There is also a new type of interactive visualisation based on HoloViews, documentation is available here: https://ubermag.github.io/documentation/notebooks/discretisedfield/field-holoviews-visualisation.html (interactivity is not available on the website, only in a running notebook)
