 note = {We investigated the magnetic field dependence of inter-grain phase transitions in the ceramic YBa2Cu3O7−δ. To this end, we measured the temperature dependences of the nonlinear magnetic responses and the current–voltage characteristics under low magnetic fields. We then estimated the inter-grain temperatures of the glass and superconducting transitions. The field–temperature phase diagram of the inter-grain ordering was similar to that of YBa2Cu4O8 ceramic. The results imply the occurrence of chiral-glass ordering in ceramic cuprate superconductors under low magnetic fields., 2019 International Conference on Strongly Correlated Electron Systems (SCES2019), September 23-28, 2019, Okayama Convention Center in Okayama, Japan},
