How to corelate experimental Tc and MH hystersis loop in CoFe2O4 and CoFe2-xAlO4

[Tulshidas Darvade]

Hello everyone,
I am new to this field and would like to understand the correlation between the experimental Curie temperature (Tc) and the M–H hysteresis behavior of CoFe₂O₄ and Al-substituted CoFe₂₋ₓAlₓO₄ ferrites. I am interested in calculating the theoretical Tc and comparing it with experimental results using simulations. However, I am unsure how to begin the simulation process. I would appreciate a step-by-step guide on preparing the required input and material files, as well as guidance on relating simulation parameters such as exchange interactions and magnetic anisotropy to experimental Tc and hysteresis loops. I currently have limited prior knowledge of the simulation approach.  

Thank you

For getting started, there is the following.

Curie temperature simulation tutorial: https://vampire.york.ac.uk/tutorials/simulation/curie-temperature/

Curie temperature simulation YouTube video: https://www.youtube.com/watch?v=W5ivNgUklr8

Curie temperature simulation workshop examples: https://github.com/richard-evans/vampire-workshop/tree/master/input-files/1_intro

There has been a recent thread of discussions on VAMPIRE CoFe2O4 simulations in the group with one of the posts in that thread here: https://groups.google.com/g/vampire-users/c/XGacgJv5r-A/m/dDvoPqMzCgAJ

An article with more about advanced Curie temperature simulations with re-scaling to correlate with experiment should be here: https://arxiv.org/abs/1409.7397v2
