Our goal is to observe possible HQF using magnetoresistance measurements to reproduce the first discovery as well as to try to utilize the phenomenon for research toward manipulation of Majorana quasiparticles. We fabricated micro rings of Sr2RuO4 using the focused ion beam technique and observed magnetoresistance oscillations that show good agreement with theoretical simulations for the Little-Parks oscillations. With careful analysis of the data, features that can be attributed to HQF were observed under additional in-plane magnetic fields .
