Magnetic field induced reversed (Negative) magnetization for electrochemically deposited Tc = 260 K Oxidized Films of Chromium Cyanide Magnets

Molecule‐based magnets with high ordering temperatures Tc (above room temperature) include some mixed‐oxide hexacyanometallates. The example studied here, Cr2.12(CN)6 · ½ H2O (the Figure shows its crystalline and amorphous phases), is shown to have Tc equals; 260 K and exhibit negative (reverse) magnetization. An explanation is suggested for this behavior and the temperature and field dependences of the magnetization. magnified image
