Seamless observation : Magnetic measurements in a solid‐state electrochemical environment have been developed and applied to a mixed‐valent chromium Prussian blue analogue (PBA) ferrimagnet. Battery cells containing PBA as a cathode active material were inserted into a SQUID and the PBA reduction during battery discharge was controlled. Magnetic changes were revealed that can be understood by the redox‐induced spin changes of the Cr ions.
