    Blue-Based Magnetic Films

## Description

- description: Knowledge of the magnetic domain is indispensable for understanding
    the magnetostatic properties of magnets. However, to date, the magnetic domain
    has not yet been reported in the field of molecule-based magnets. Herein, we study
    the magnetic domains of molecule-based magnets. Two magnetic films of iron/chromium
    hexacyanidochromate FexCr1−x[Cr-(CN)6]2/3・5H2O (x = 0; Film 1 and x = 0.2; Film
    2) were prepared for investigation. The temperature evolution of surface magnetization
    was measured using magnetic force microscopy. Film 1 showed a magnetic domain
    below Curie temperature (TC) and its positive-magnetic polarization increased
    monotonously with decreasing temperature, while Film 2 showed positive magnetic
    polarization below TC and switches from positive to negative magnetization through
    a demagnetization state at 146 K. This study originally reports the temperature
    variation of the magnetization state at the magnetization reversal. The magnetic
    domains appeared as a maze pattern with an approximate domain size of one-to-several
    micrometers. This work shows that research on molecule-based magnets can be expanded
    from magnetochemistry to the magnetostatic engineering of bulk magnets, molecule-based
    magnetostatic engineering.
