Origin of Ferroelectricity in Orthorhombic LuFeO
Ujjal Chowdhury, Sudipta Goswami, Amritendu Roy +13
We demonstrate that small but finite ferroelectric polarization (0.01 C/cm) emerges in orthorhombic LuFeO () at (600 K) because of commensurate (…
Origin of magnetic moments and presence of a resonating valence bond state in BaYIrO
Abhishek Nag, Sayantika Bhowal, M. M. Sala +10
While it was speculated that 5 systems would possess non-magnetic ~=~0 ground state due to strong Spin-Orbit Coupling (SOC), all such systems have invariably shown presence…
Effect of Frustrated Exchange Interactions and Spin-half Impurity on the Electronic Structure of Strongly Correlated NiFeO
Kodam Ugendar, S. Samanta, Sudhendra Rayaprol +3
Spin-polarized density functional calculations, magnetization, and neutron diffraction measurements are carried out to investigate the magnetic exchange interactions and strong cor…
Large magnetoelectric coupling in nanoscale BiFeO 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 at room temperature under zero and 20 kOe magnetic field. We noticed a sup…
Improper Ferroelectricity in Helicoidal Antiferromagnet Cu3Nb2O8
G. Sharma, J. Saha, S. D. Kaushik +2
Cu3Nb2O8 is an unusual multiferroic compound that undergoes a series of magnetic ordering at low temperatures. Concurrent development of electric polarization has been reported at…
Correlation of magneto-electric coupling with crystal structure in Dy doped hexagonal YMnO3
A. K. Singh, S. D. Kaushik, V. Siruguri +1
Coexistence of mutually influencing ferroelectric and magnetic ordering at low temperature in hexagonal phase of rare-earth manganites gives rise to interesting physical phenomena.…
