Nonmonotonic particle-size-dependence of magnetoelectric coupling in strained nanosized particles of BiFeO

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…

Evidence for two spin-glass transitions with magnetoelastic and magnetoelectric couplings in the multiferroic (BiBa)(FeTi)O system

Arun Kumar, S. D. Kaushik, V. Siruguri +1

For disordered Heisenberg systems with small single ion anisotropy, two spin glass transitions below the long range ordered phase transition temperature has been predicted theoreti…

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…

Atomic scale chemical fluctuation in LaSrVMoO6: A proposed halfmetallic antiferromagnet

Somnath Jana, Vijay Singh, S. D. Kaushik +7

Half metallic antiferromagnets (HMAFM) have been proposed theoretically long ago but have not been realized experimentally yet. Recently, a double perovskite compound, LaSrVMoO6, h…
