In this work, two Morin transitions were observed in hematite product at the intermediate stage during the oriented attachment process, which is universal and plays an important role in biogeochemical processes that shape Earth's near-surface environments. Seemingly, these Morin transitions originate from the existence of two sizes of hematite particles. While in-depth study reveals that they were also interdependent on the defreezing behaviors of two different spin configurations at their interfaces. Such pioneering study on the magnetic performance during the oriented attachment process provides a fundamental and new physical basis for the materials' potential applications.
