Enhanced negative capacitance in La-doped Pb(Zr $_{0.4}$ Ti $_{0.6}$ )O $_{3}$ ferroelectric capacitor from tuning of bias voltage pulse

Ganga S. Kumar, Sudipta Goswami, Subhashree Chatterjee +5

We report a remarkable bias voltage dependent specific negative capacitance in multidomain La-doped Pb(Zr $_{0.4}$ Ti $_{0.6}$ )O $_{3}$ (PLZT) ferroelectric capacitors. The specific nega…

Evidence of spin reorientation transition below 150 K from magnetic force microscopy in a ferromagnetic BiFeO $_{3}$ thin film

Sudipta Goswami, Shubhankar Mishra, Kishor Kumar Sahoo +8

We investigated the magnetic transitions in BiFeO $_{3}$ at low temperature (5-300 K) and observed nearly 90 $^{o}$ rotation of magnetic domains (imaged by vertical magnetic force micros…
