Ferroelectric hysteresis loop (left) and magnetic hysteresis loop (right) measured at room temperature indicate the coexistence of ferroelectricity and ferromagnetism. Disclaimer: AAAS and EurekAlert!
Figure (a–d) Tunable asymmetric Hall loops at 5 K (magnetic histories are shown in insets). (e) Symmetric loops under high enough external magnetic field. (f) Sketch of the influence of positively ...
