Temperature Dependence of the Magnetic Properties of IrMn/CoFeB/Ru/CoFeB Exchange Biased Synthetic Antiferromagnets
Round 1
Reviewer 1 Report
Albisetti et al. report in this paper on the temperature dependence of the magnetic properties of four synthetic antiferromagnets (or SAFs) based on different IrMn/CoFeB/Ru/CoFeB sets of samples. These samples were grown on a Si/SiO2 substrate by employing the magnetron sputtering technique. The magnetic hysteresis loops were studied along both the easy and hard axes. Overall, the work is performed correctly and reaches the standard of the journal Materials. So that, my recommendation is to publish the paper, but after the following revisions.
Some minor points:
In page 35: the authors should change “wild” for another more suitable word.
The authors should increase the number of references related to SAFs used in magnetic tunnel junctions (since only one reference is quoted, Ref.[5]).
In page 75, in the sentence “The as grown samples ...” seems that there is something wrong. Please, check it out.
A “conclusions” section should be add, after that of “discussion”.

Reviewer 2 Report
The authors describe their investigation of the temperature dependence of the magnetic properties of exchange bias systems based on CoFeB and IrMn. The results are well presented and should definitely be published in materials as an article. I have only a few remarks: -) Have the Co40Fe40B20 layers been sputtered from one single target or co-sputtered? Were different stoichiometries also tried or why do the authors use exactly this stoichiometry? There are strong variations of the magnetic behavior depending on the manufacturing method (dc, rf etc.), gas pressure, working distance, stoichiometry etc. -) How was the stoichiometry and layer growth characterized after the manufacturing and after the field cooling procedure? The results in Fig2 and Fig3 show, that the compensation of the two F layers is not exact, (Set A, B and D). The authors mention this, but say nothing about possible investigations in this respect. -) Were other coating thicknesses (0.7nm) also produced? Was the typical oscillatory behaviour of the coupling strength observed? -) How do the authors define Hex, or how were the values for Hex from the measurements extracted? -) Was the layer system also inverted, i.e. was it produced and compared with the AF first?Author Response

Reviewer 3 Report
Dear Editor,
The authors presented the results concerning the temperature and angular dependence of the magnetic properties of exchange biased synthetic antiferromagnets - Si/SiO2/Co40Fe40B20(25,35)/Ru(0.6,0.7/Co40Fe40B20 (25,35)/IrMn 10/ Ru 2. I suggest the authors to compare their results with these from other authors. It will be more useful for readers.
Sincerely yours
