Based on the principle of the biomimetic mineralization and with the aspartic acid as the biomolecule inducer, the magnetotactic wood is prepared through the deposition of the MnFe₂O₄ crystal on the wood surface via the solvothermal method at low temperature. The asprepared wood is characterized by the X-ray diffraction (XRD), the scanning electron microscopy (SEM), the Fourier transform infrared spectroscopy (FT-IR), the vibrating sample magnetometer (VSM) and the vector network analysis (VNA). The results show that the magnetic MnFe₂O₄ could be deposited on the wood surface to form the magnetotactic wood induced by the aspartic acid under the alkaline solvothermal mineralization at low temperature. A minimum reflection loss of the magnetotactic wood is-12 dB at 15.52 GHz. Simultaneously, the RL is below-12 dB ranging from 14 to 17 GHz. Therefore, the magnetotactic wood would find a great potential application for preventing the indoor electromagnetic wave pollution.
