I think the Scientometrics journal would be the best place for you to find the best paper on Scientometrics.

http://link.springer.com/journal/11192

Then you can go for the COLLNET Journal.

For informetrics you can go for the Journal of Informetrics from Elsevier

www.journals.elsevier.com/journal-of-informetrics/

Then other Indian Journals like Annals and DJLIT also contain some good articles on Scientometrics.

All the best for your research.
