Abstract
<p>Substituting cobalt for iron in perovskite bismuth ferrite changes its spin structure from cycloid to collinear and induces canted spin spontaneous magnetization perpendicular to the electric polarization. Magnetization reversal by electric field was demonstrated in thin films on GdScO3 substrates by observing ferroelectric and magnetic domains at the same area. The different manner of magnetization reversal depending on the poling direction is also discussed. This characteristic is expected to be utilized as an ultra-low-energy-consuming non-volatile magnetic memory device that enables writing information by electric field.</p>
