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…
Effect of rare-earth (Er and Gd) substitution on the magnetic and multiferroic properties of DyFe0.5Cr0.5O3
Mohit K. Sharma, Tathamay Basu, K. Mukherjee +1
We report the results of our investigations on the influence of partial substitution of Er and Gd for Dy on the magnetic and magnetoelectric properties of DyFe0.5Cr0.5O3, which is…
Multiglass properties and magnetoelectric coupling in uniaxial anisotropic spin-cluster-glass Fe2TiO5
Shivani Sharma, Tathamay Basu, Aga Shahee +3
The compound, Fe2TiO5 (FTO)is a well-known uniaxial anisotropic spin-glass insulator with two successive glassy freezing temperatures i.e. transverse (TTF= 9K) and longitudinal (TL…
Magnetic and dielectric behavior of the spin-chain compound Er2BaNiO5 well below its Néel temperature
Tathamay Basu, Kiran Singh, N. Mohapatra +1
We have recently reported that the Haldane spin-chain system, Er2BaNiO5, undergoing antiferromagnetic order below 32 K, is characterized by the onset of ferroelectricity near 60K d…
Displacive-type ferroelectricity from magnetic correlations within spin-chain
Tathamay Basu, V. V. Ravi Kishore, Smita Gohil +8
Observation of ferroelectricity among non-d0 systems, which was believed for a long time an unrealistic concept, led to various proposals for the mechanisms to explain the same (i.…
