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…

Room-temperature multiferroicity in GaFeO $_{3}$ thin film grown on (100)Si substrate

Sudipta Goswami, Shubhankar Mishra, Kausik Dana +7

Room-temperature magnetoelectric multiferroicity has been observed in c-axis oriented GaFeO $_{3}$ thin films (space group $P na 2_{1}$ ), grown on economic and technologically important (…

Nonmonotonic particle-size-dependence of magnetoelectric coupling in strained nanosized particles of BiFeO $_{3}$

Sudipta Goswami, Dipten Bhattacharya, Chandan K. Ghosh +4

Using high resolution powder x-ray and neutron diffraction experiments, we determined the off-centered displacement of the ions within a unit cell and magnetoelectric coupling in n…

Spontaneous exchange bias in a nanocomposite of BiFeO $_{3}$ -Bi $_{2}$ Fe $_{4}$ O $_{9}$

Tuhin Maity, Sudipta Goswami, Dipten Bhattacharya +2

We have observed a large as well as path-dependent spontaneous exchange bias (H $_{S E B}$ ) ( $\sim$ 30-60 mT) in a nanocomposite of BiFeO $_{3}$ -Bi $_{2}$ Fe $_{4}$ O $_{9}$ across 5-300 K when it i…

A Training effect on electrical properties in nanoscale BiFeO $_{3}$

Sudipta Goswami, Dipten Bhattacharya, Wuxia Li +3

We report our observation of the training effect on dc electrical properties in a nanochain of BiFeO $_{3}$ as a result of large scale migration of defects under combined influence of…
