mumax2

Dear mumax community, The minor patch 3.11.1 has now been released, which solves a couple of bugs.

Hi! Regarding the script itself, I see autosave() in the last line. That means that the dynamics

Hi, In base mumax3, you can include an effective field. You need to set the magneto-elastic coupling

Hi Josh, Thanks a lot for clarifying — that makes perfect sense now. Really appreciate you pointing

Dear all, Is it possible to excite the breathing modes of the skyrmions using a resonant SOT drive (

Dear all, Hoping someone can help me solving this problem. I also want to ask how to determine to use

Dear Josh, Thank you very much for your explanation! I have successfully solved my problem according

Hi, I would double check your visualization. That does indeed produce an ellipse on top of a cuboid:

Dear All, I have found a solution, thank you! REgards, Bingjin On Tue, Sep 2, 2025 at 11:29 AM Georg

Dear all, I know that we can use cylinder(D, h) to create a 3D cylinder with diameter D and height h,

Hi, Yes, you can do FixedLayer.Add(), the same way you would do it for B_ext.Add(), or J.Add(). For

Thank you for your response. Regards, Mani On Sat, 30 Aug, 2025, 6:36 am Josh Lauzier, <

Thank you for the clarification. I will try this method. I am trying to add SOT as custom field with

Hi, Yes, in that case both anisotropies will favor being in-plane, so the result should be in-plane.

Hi, Please post the script (or both variations of the script) that you're having issues with. It

Thank you sir for the reply. On Tue, Aug 26, 2025 at 9:24 PM Felipe Garcia <pkwga...@gmail.com

Hi, Based on your wording, I assume you want to use this for a custom field term, not just save them?

Thank you for your reply. I made such a simple mistake. I will make sure to check the GUI carefully

Hi, I see two major issues, at least. One,in your analytic expression for the field, remember that

Hi, It depends on what exactly you're trying to simulate. Using an effective medium approximation

Hi, Sorry, that was my mistake, there are a few typos. It would instead be something like Rect(a1,W).

Thank you for your explanation!I've solved the questions above in Comsol.I am currently

Dear Ian, Thank you very much for your prompt reply and for providing the code. It is working

Hi, If you're doing Slonczewski STT, you should define all the relevant terms (including lambda,

Hi, The fixed and spacer layers are not modeled explicitly in mumax, only the free layer is. You can

"I want to set up a structure with two Bloch domain walls, as shown in the figure. The steps are

Hi, If you're comfortable compiling mumax3, the master branch of the github repository contains a

I am Vivek Kumar, currently working on simulating photon–magnon coupling in hybrid cavity–magnon

Respected sir Dr. Jonathan Leliaert Dr. Jeroen Mulkers Dr. Josh Lauzier Sir, I am encountering an

Thank you very much for your reply. After modifying the correct damping coefficient, I obtained the

Hi All, I am currently learning MuMax and would like to start with a simple STT-MTJ switching example
