Novel dielectric anomalies due to spin-chains above and below Neel temperature in Ca3Co2O6
Tathamay Basu, Kartik K Iyer, Kiran Singh +1
We bring out novel dielectric behavior of a spin-chain compound, Ca3Co2O6, undergoing Neel order at (T_N=) 24 K. It is found that the virgin curve in the plot of isothermal dielect…
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…
A fluid-mechanical model of elastocapillary coalescence
Kiran Singh, John R. Lister, Dominic Vella
We present a fluid-mechanical model of the coalescence of a number of elastic objects due to surface tension. We consider an array of spring-block elements separated by thin liquid…
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…
Magnetoelectric coupling in Haldane spin chain system, Dy2BaNiO5
Kiran Singh, Tathamay Basu, S. Chowki +4
We report the results of various measurements, namely magnetization, complex dielectric permittivity and electric polarization (P) on Dy2BaNiO5 as a function of temperature (T) and…
