Respected researchers,
I am attaching herewith an M_H curve. Here the sample may possess both FM and AFM/PM behaviours. In order to identify the contribution of both magnetic behaviours, I used this equation, M = Ms*(pi/2)*((arctan (H + Hc/Hc)tan(pi*S/2)) + chi*H (Journal of Alloys and Compounds 867 (2021) 159008). Here, how to calculate the susceptibility from the M-H curve (or) how to extract dM/dH from M-H data to identify the PM/AFM behaviour. please help me in this regard. Thanks in advance.
with kind regards,
R. Rajesh
Dear Dr. R. Rajesh,
For exact explanation about your queries using the equation: M = Ms*(pi/2)*((arctan (H + Hc/Hc)tan(pi*S/2)) + chi*H, contact to the corresponding/first author of the article Journal of Alloys and Compounds 867 (2021) 159008.
Good Luck
Dinesh
Dear R. Rajesh,
A work carried out by Sang-Koog Kim [1] provides a very well description of how to apply the model you mentioned (see attached image) for estimating FM and PM/AFM contributions to magnetization curves. I recommend you read his/her work because it clearly shows how to fit this equation into experimental data for quantifying those contributions.
Moreover, I think the work carried out by S. Duhalde [2] could be also useful for your purpose because it shows the application of the same model.
If you need further assistance with the analysis of your curves by using this model, I would like to collaborate with you.
Kind regards,
Simón Roa.
