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…
Linear magnetoelectric effect as a signature of long-range collinear antiferromagnetic ordering in the frustrated spinel CoAl2O4
Somnath Ghara, N. V. Ter-Oganessian, A. Sundaresan
The ground state of the frustrated A-site magnetic spinel CoAl2O4 has been a controversial issue whether it is a collinear antiferromagnetic ordering or a spiral spin - liquid stat…
Structural and magnetic properties of a new and ordered quaternary alloy MnNiCuSb (SG: F-43m)
Zeba Haque, Gohil S. Thakur, Somnath Ghara +3
We have synthesized a new crystallographically ordered quaternary Heusler alloy, MnNiCuSb. The crystal structure of the alloy has been determined by Rietveld refinement of the powd…
Effect of internal electric field on ferroelectric polarization in multiferroic TbMnO
Chandan De, Somnath Ghara, A. Sundaresan
Pyro-current measurements have been widely used to study ferroelectric properties in multiferroic materials. However, determination of intrinsic polarization by this method is not…
Temperature dependent magnetic, dielectric and Raman studies of partially disordered La2NiMnO6
Pradeep Kumar, S. Ghara, B. Rajeswaran +3
We report a detailed magnetic, dielectric and Raman studies on partially disordered and biphasic double perovskite La2NiMnO6. DC and AC magnetic susceptibility measurements show tw…
