Origin of Ferroelectricity in Orthorhombic LuFeO $_{3}$

Ujjal Chowdhury, Sudipta Goswami, Amritendu Roy +13

We demonstrate that small but finite ferroelectric polarization ( $\sim$ 0.01 $μ$ C/cm $^{2}$ ) emerges in orthorhombic LuFeO $_{3}$ ( $P nma$ ) at $T_{N}$ ( $\sim$ 600 K) because of commensurate (…

Determination of intrinsic ferroelectric polarization in lossy improper ferroelectric systems

Ujjal Chowdhury, Sudipta Goswami, Dipten Bhattacharya +2

We measured the intrinsic hysteretic polarization in lossy improper and nanoferroelectric systems where the nonhysteretic polarization and leakage are large and the relaxation take…

Room temperature multiferroicity in orthorhombic LuFeO $_{3}$

Ujjal Chowdhury, Sudipta Goswami, Dipten Bhattacharya +3

From the measurement of dielectric, ferroelectric, and magnetic properties we observe simultaneous ferroelectric and magnetic transitions around $\sim$ 600 K in orthorhombic LuFeO$_…

Large magnetocapacitance in electronic ferroelectric manganite systems

Ujjal Chowdhury, Sudipta Goswami, Dipten Bhattacharya +4

We have observed a sizable positive magnetocapacitance ( $\sim$ $5 - 90%$ ) in perovskite Pr $_{0.55}$ Ca $_{0.45}$ MnO $_{3}$ and bilayer Pr(Sr $_{0.1}$ Ca $_{0.9}$ ) $_{2}$ Mn $_{2}$ O $_{7}$ system under…
