Magnetic material, and memory and sensor using same

摘要

A magnetic material composed of epsilon-In_xFe_2-xO₃ (wherein 02O₃ crystal. The crystal exhibits an X-ray diffraction pattern similar to that of an epsilon-Fe₂O₃ crystal structure and has the same space group as that of an epsilon-Fe₂O₃. The In content imparts to the magnetic material a magnetic phase transition temperature that is lower than that of the epsilon-Fe₂O₃ and a spin reorientation temperature that is higher than that of the epsilon-Fe₂O₃. The In content can also give the magnetic material a peak temperature of the imaginary part of the complex dielectric constant that is higher than that of the epsilon-Fe₂O₃.
