Cooperative Ru(4d)-Ho(4f) magnetic orderings and phase coexistence in the 6H-perovskite multiferroic Ba3HoRu2O9
T. Basu, V. Caignaert, F. Damay +3
We report cooperative magnetic orderings in a 6H-perovskite multiferroic system, Ba3HoRu2O9, via comprehensive neutron powder diffraction measurements. This system undergoes long-r…
Enhancement of magnetodielectric coupling in 6H-perovskites Ba3RRu2O9 for heavier rare earth cations (R=Ho,Tb)
Tathamay Basu, Vincent Caignaert, Somnath Ghara +5
The role of rare-earth (R) ions on the magnetodielectric (MD) coupling is always intriguing and markedly different for different systems. Although many reports are available concer…
Designing of a magnetodielectric system in hybrid organic-inorganic framework, a perovskite layered phosphonate MnO3PC6H4-m-Br.H2O
Tathamay Basu, Clarisse Bloyet, Felicien Beaubras +11
The research on multiferrocity and magnetoelectric coupling in metal-organic system is rare. Very few hybrid organic-inorganic frameworks (HOIF) exhibit direct magnetoelectric coup…
Nanoscale ordered Layered-Segregation of Cobalt and Iron in the Perovskite SmFe0.5Co0.5O3
Nathalia E. Mordvinova, Ashish Shukla, Asish K. Kundu +4
The possibility to segregate cobalt and iron in a single perovskite, at a nanoscale in the form of layers has been investigated, using sol gel technic synthesis. Quite remarkably,…
Incipient spin-dipole coupling in a 1D helical-chain metal-organic hybrid
Tathamay Basu, Clarisse Bloyet, Jean-Michel Rueff +5
Low dimensional magnetic systems (such as spin-chain) are extensively studied due to their exotic magnetic properties. Here, we would like to address that such systems should also…
Gigantic magnetic field polarization and magnetoelectric coupling in a ferrimagnetic oxide CaBaCo4O7
V. Caignaert, A. Maignan, K. Singh +7
The single crystal study of CaBaCo4O7, a non collinear ferrimagnet (TC=64K), with a polar orthorhombic space group (Pbn21) between 4 K and 293 K, shows the appearance below TC of a…
