Large magnetoelectric coupling in nanoscale BiFeO${}_3$ from direct electrical measurements

Sudipta Goswami, Dipten Bhattacharya, Lynette Keeney +9

We report the results of direct measurement of remanent hysteresis loops on nanochains of BiFeO${}_3$ at room temperature under zero and $\sim$20 kOe magnetic field. We noticed a sup…
