The reception of Popper in Japan has not been a glorious history up to the present day. There have been numerous misunderstandings and distortions. It is important to record and discuss them in order to learn from them and to make use of his ideas in

We report dielectric and magnetic properties of a single crystal of LuFe 2 O 4 with different degrees of oxygen deficiency. The oxygen stoichiometry was monitored with the gas mixture ratio of CO 2 and CO during the crystal growing process. A sample

We investigated the effect of oxygen annealing on dielectric properties of LuFeCuO4 mainly by dielectric measurements and transmission electron microscopy experiments. It was found that the leakage current density decreases with high-pressure oxygen

Rare-earth iron oxides of the form RFe2O4 (R = Y, Ho–Lu) show a new mechanism of ferroelectricity owing to the charge ordering of Fe ions below ~330 K. To determine the physical properties of this system, the magnetic and dielectric properties of H

The magnetic and dielectric properties of InFe2O4, InFeCuO4, and InGaCuO4 have been investigated. All these materials are isostructural with RFe2O4 (R = Y, Ho-Lu), which shows ferroelectricity due to iron-valence ordering. InFe2O4 exhibits ferrimagne
