The points represented by blue markers are determined by the ε–H measurements in a pulsed magnetic-field [Fig. 3e], while those shown by red markers are obtained from the ε–T measurements in a persistent magnetic-field data shown in Fig. 5a. The black open circles correspond to the phase boundary of pristine Ba2CoGe2O7, which are collected from ref. 22.
