A transition from temperature independent magnetic susceptibility peak to dip was observed in MoSe2−xTex (x = 0.1, 0.2, 0.4, 0.8) single crystals with increasing Te replacement. The magnetic susceptibility peak was found to originate from ferromagnetism, consistent with previous results. From the Raman spectrum, we infer 1T structure on predominantly 2H structure is the origin of ferromagnetism. In addition, the temperature independent susceptibility dip is likely to originate from a mixture of a diamagnetic contribution from 2H structure and a paramagnetic contribution from 1T structure.

The work presented in this manuscript is an experimental study of structure induced magnetic susceptibility peak to dip transition in the MoSeTe system when concentration of Se (respectively Te) varies. The experimental results seem correct to me and the interpretation is reasonable. However, I am not entirely convinced of the fundamental importance of this study. From this point of view, the manuscript lacks any substantial introduction to situate the importance of this work in relation to results already existing in the literature, particularly those published by the authors of this manuscript (Refs. 7, 8, 9,10):
(1) For instance, the authors have already published a study on the WSeTe system when concentration of Se (respectively Te) varies . I think it is important to discuss what is new and interesting about replacing W with Mo…
(2) In addition, the authors currently have submitted a paper to SciPost on MoSe1.8Te0.2 (Scipost_202306_00009v1.pdf). The two studies are admittedly different in that the present article (scipost_202308_00010v1) deals with the effect on susceptibility of structural changes, while the other (scipost_202306_00009v1) focuses on the study of susceptibility for a specific concentration. But is it necessary to make two distinctly short articles, when SciPost does not impose a "letter" format? In any case, I do not understand why the present manuscript does not even cite scipost_202306_00009v1.
(3) Secondary remark, but important nonetheless: No reference numbers are given in the main text of the manuscript. And the format (template latex) is not that of SciPost.
1- A major revision of the manuscript is needed to show the importance of this work in relation to results already published in this field.
2- Combine this manuscript with scipost_202306_00009v1 is perhaps a good idea to obtain a more substantial article that better corresponds to the expectations of Scipost physics.
3- Correct the manuscript according to note (3) of my report.
This manuscript concerns the magnetic response of MoSe2−xTex, and argues that the apparent ferromagnetic response originates from structural disorder between 1T and 2H structures. Given the similarity in subject matter and conclusions to another recent submission by the authors, "An anisotropic temperature independent magnetic susceptibility peak in a van der Waals layer structure MoSe1.8Te0.2" (scipost_202306_00009v1), I would recommend the authors to combine both submissions into a single manuscript.
