Evidence of ferromagnetic short-range correlations in cubic La1-xSrxMnO3-δ (x=0.80, 0.85) above antiferromagnetic ordering
Aga Shahee, Kiran Singh, R. J. Choudhary +1
We report the existence of ferromagnetic correlations (FMC) in paramagnetic (PM) matrix of cubic La1-xSrxMnO3-δ (x = 0.80, 0.85) well above its coupled structural, magnetic and ele…
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…
Anisotropic magnetodielectric coupling behavior of Ca3Co1.4Rh0.6O6 due to geometrically frustrated magnetism
Tathamay Basu, Kartik K. Iyer, Kiran Singh +3
We have investigated the magnetic, dielectric and magnetodielectric (MDE) behavior of a geometrically frustrated spin-chain system, Ca3Co1.4Rh0.6O6, in the single crystalline form…
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.…
Modifications in the frustrated magnetism, oxidation state of Co and magnetoelectric coupling effects induced by a partial replacement of Ca by Gd in the spin chain compound Ca3Co2O6
Tathamay Basu, Kiran Singh, E. V. Sampathkumaran
We have systematically investigated the influence of gradual replacement of Ca by Gd on the magnetic and complex dielectric properties of the well-known geometrically frustrated sp…
Analysis of the multiferroicity in the hexagonal manganite YMnO3
Kiran Singh, Marie-Bernadette Lepetit, Charles Simon +4
We performed magnetic and ferroelectric measurements, associated with Landau theory and symmetry analysis, in order to clarify the situation of the YMnO3 system, a classical exampl…
