Origin of destruction of multiferroicity in Tb2BaNiO5 by Sr doping and its implications
Ram Kumar, S. Rajput, T. Maitra +6
The orthorhombic Haldane spin chain compound Tb2BaNiO5 (Neel order, TN1= 63 K) has been shown to be an exotic multiferroic system below (TN2) 25 K due to various fascinating featur…
Destruction of multiferroicity in Tb2BaNiO5 by Sr doping and its implication to magnetoelectric coupling
Sanjay K Upadhyay, E. V. Sampathkumaran
The Haldane spin-chain compound, Tb2BaNiO5, with two antiferromagnetic transitions, one at T1=63K, and the other at T2=25K, has been recently shown by us to be an exotic multiferro…
Existence of a critical canting angle of magnetic moments to induce multiferroicity in the Haldane spin-chain system, Tb2BaNiO5
Ram Kumar, Sudhindra Rayaprol, Sarita Rajput +5
We report an unusual canted magnetism due to 3d and 4f electrons, occupying two different crystallographic sites, with its consequence to electric dipole order. This is based on ne…
Neutron diffraction study of a metallic kagome lattice, Tb3Ru4Al12
Sudhindra Rayaprol, Andreas Hoser, Kartik K Iyer +2
We present the results of neutron diffraction studies on polycrystals of a metallic kagome lattice, Tb3Ru4Al12, reported recently to undergo reentrant magnetism, with the onset of…
Anisotropic re-entrant spin-glass features in a metallic kagome lattice, Tb3Ru4Al12
E. V. Sampathkumaran, Kartik K Iyer, Sanjay K Upadhyay +1
We report the results of ac and dc magnetic susceptibility and isothermal magnetization measurements (T= 2-300 K) on the single crystals of a metallic kagome lattice, Tb3Ru4Al12, r…
Multiferroicity in a spin-chain compound, Tb2BaCoO5, with exceptionally large magnetodielectric coupling in polycrystalline form
Sanjay K Upadhyay, E. V. Sampathkumaran
We report the results of detailed investigations of magnetization, heat-capacity, dielectric, pyrocurrent, and magneto(di)electric measurements on Tb2BaCoO5, belonging to a hither-…
