Modelling of Magnetic Stray Fields in Multilayer Magnetic Films with In-Plane or Perpendicular Anisotropy
Round 1
Reviewer 1 Report
The manuscript “magnetochemistry-2035479” deals with the theoretical modeling of magnetic stray fields in multilayer magnetic films by considering the in-plane and perpendicular anisotropy. The model is based on Maxwell’s magnetostatics theory.
The manuscript is well-written and the outcome of the work is clear. However, I have a few questions before accepting the manuscript.
The authors have considered a hard and a soft Ferromagnetic layer. Why did the author choose this particular set? What will be the outcome if both the FM layers are hard or soft?
As a tunnel barrier, the authors have chosen a Non-magnetic spacer. What will be the scenario for the paramagnetic spacer?
What possible changes may occur for the heterostructures stacking?

Reviewer 2 Report
The Authors showed a very interesting work about multilayer magnetic films studying the effect of in-plane or perpendicular anisotropy.
This work can be considered very appealing for the development of new magnetic devises as a kind of field effect transistors.
The manuscript should be accepted with minor review and here below my comments.
1) The authors at the row 29 in the Introduction when are mentioned the applications they should mention also the possibility to produce 2D field effect transistors to detect magnetism as previously developed pressure [ACS nano 15 (4), 6861-6871 (2021)] or temperatures field effect transistors.
2) At the line 50 in the introduction I suggest the authors to mention frustrated antiferromagnetic materials as Y114 and manganese where the cutting of kagome lattice should leave us something to reflect and specially I suppose that in case of Y114 (classical example of frustrated anti ferromagnetic material) the Jahn-Teller effect will change with consequences on the ferromagnetic order [Dalton Transactions 47 (15), 5483-5491 (2018)].
3) At line 100 the word ferromagnet should be substituted with ferromagnetic compound.
4) The fonts in Figure 6 should be bigger because I cannot read

Reviewer 3 Report
The work is devoted to the numerical modeling of magnetic fields in magnetic sandwich structures. The work does not contain a sufficient amount of new material and does not have a degree of originality sufficient for publication. The main remarks are as follows:
1. The standard methodology of numerical simulation of magnetic fields in COMSOL is applied in this work. The results can be regarded only as an exercise in the use of COMSOL, but not as an original scientific research.
2. The authors present as one of the results a correctness check of the expression ? = ?0(? + ?); but this expression is the definition of the relationship of the magnetic field vectors B and H, it cannot be incorrect.
3. At the beginning of Section 2, the reasoning about the character of the magnetic field is incorrect, including the statement that "The magnetic circuits of the dipole field H lines are not closed." The H field lines are always closed. Accordingly, the field lines in Fig. 1b are incorrectly depicted. The field lines in this case have the form depicted, for example, in https://en.wikipedia.org/wiki/Demagnetizing_field#/media/File:VFPt_magnets_BHM.svg
In summary, the paper cannot be recommended for publication.

Reviewer 4 Report
The authors have described a theoretical understanding of the distribution of magnetic stray fields around thin-film nanostructures.
The manuscript is well-written and ready for broad readers.
I would recommend authors compare their results with experimental data. It will help to check the applicability of the model described in the paper.
Please describe the limitations of the model and its applicability for an actual device structure.
If the film thickness is of sub-nm order, does the model still applicable? If yes, please demonstrate one result.
If not, what thickness of the film is allowed for this model?
There are disorders, voids, or vacancies. Can we incorporate into the model?

Reviewer 3 Report
The authors have corrected the article in accordance with the comments made earlier. However, my main comment on the degree of novelty and originality, in principle, remains valid. However, it is the prerogative of the editorial board to decide whether an article is acceptable for publication in terms of the degree of originality. If the editorial board considers the originality of the article to be sufficient, I also do not prevent its publication.
