The application of magnetic fields in the oxygen reduction/evolution reaction (ORR/OER) testing for electrocatalysts has attracted increasing interest, but it is difficult to characterize on-site surface reconstruction.

Magnetic characterizations indicate that FeCo O -M shows the spin-state transition of cations from a low-spin state to an intermediate-spin state compared with FeCo O .
