Herein, we report a single-nanosize (i.e., less than ten nanometers across) hard magnetic ferrite. This magnetic ferrite is composed of \u03b5-Fe2O3, with a sufficiently high Hc value for magnetic recording systems and a remarkably high magnetic anisotropy constant of 7.7\u2009\u00d7\u2009106\u2009erg cm\u22123. For example, 8.2-nm nanoparticles have an Hc value of 5.2\u2009kOe at room temperature. A colloidal solution of these nanoparticles possesses a light orange color due to a wide band gap of 2.9\u2009eV (430\u2009nm), indicating a possibility of transparent magnetic pigments. Additionally, we have observed magnetization-induced second harmonic generation (MSHG). The nonlinear optical-magnetoelectric effect of the present polar magnetic nanocrystal was quite strong. These findings have been demonstrated in a simple iron oxide, which is highly significant from the viewpoints of economic cost and mass production.","subitem_description_type":"Abstract"}]},"item_2_description_6":{"attribute_name":"\u5185\u5bb9\u8a18\u8ff0","attribute_value_mlt":[{"subitem_description":"UTokyo
