Kiran Singh,Tathamay Basu,S. Chowki,N. Mahapotra,Kartik K. Iyer,P. L. Paulose,E. V. Sampathkumaran +6 more
TL;DR: In this article, the authors report the results of various measurements, namely magnetization, complex dielectric permittivity, and electric polarization, on Dy{}_{2}$BaNiO${}_{5}$ as a function of temperature and magnetic field, with the primary motivation of exploring the existence of magnetoelectric (ME) coupling among Haldane spin-chain systems.
Journal ArticleDOI
A reentrant phenomenon in magnetic and dielectric properties of Dy2BaNiO5 and an intriguing influence of external magnetic field.
Tathamay Basu,P. L. Paulose,Kartik K. Iyer,Kiran Singh,Niharika Mohapatra,S. Chowki,Babu Gonde,E. V. Sampathkumaran +7 more
TL;DR: It is reported that the spin-chain compound Dy2BaNiO5, recently proven by us to exhibit magnetoelectric coupling below its Néel temperature of 58 K, exhibits strong frequency-dependent behavior in ac magnetic susceptibility and complex dielectric properties at low temperatures, mimicking the 'reentrant' multiglass phenomenon.
