Round 1

Reviewer 1 Report

Authors have described a study wherein BFO nanoparticles are added into YBCO and their properties are studied. The study is interesting, however, needs a major revision at this stage for any further consideration. 

1. The motivation to add BFO nano-particles needs its place. Its not clear why BFO! 

2. The authors need to describe the sample sizes - sample dimensions that were compacted and fabricated. What sample sizes were used for ac susceptibility measurements?

3. It appears that the prepared samples are not single grains/ single crystals. If so, how was field applied during the ac susceptibility measurements? Provide photos of the processed samples. 

4. In table-1, Why is BiFeO3 content seen only 0.2% sample? why not in other samples? What is the mechanism through which this absorption/reaction happening? Needs a systematic understanding!

5. How reproducible are these results?

6. Also, some more recent works need be cited. 

I hope the authors can revise their paper and resubmit based on these lines. Good luck!

Round 2

Reviewer 2 Report

Authors did not address my comments properly.

The main comment: “Overall, the paper needs strong revision.” is completely ignored.

The added new papers on page 2 are not linked to the method. There is no reason monopolizing term "thermal treatment" for such very specific chemical method. Use of it in [7-9] is not a good argument either.

Added small fragments of text are full of mistakes, including “invention” of new material YBa2Cu3O (page 2), “a triangular shape of 5 mm x 2 mm x 1.5 mm dimensions” (page 3) and mysterious “FWHM peak” (page 5). This only adds more confusion to the manuscript.

Major revision of all text is necessary.
