Cobalt substitution induced magnetodielectric enhancement in multiferroic Bi2Fe4O9
S. R. Mohapatra, P. N. Vishwakarma, S. D. Kaushik +3
Antiferromagnetic Bi_{2}Fe_{4}O_{9} (BFO), lightly substituted by cobalt is studied for magnetodielectricity. The substitution causes a substantial decrease in the Neel temperature…
Magnetic and magnetodielectric coupling anomalies in the Haldane spin-chain system Nd2BaNiO5
Tathamay Basu, Niharika Mohapatra, Kiran Singh +1
We report the magnetic, heat-capacity, dielectric and magnetodielectric (MDE) behaviour of a Haldane spin-chain compound containing light rare-earth ion, Nd2BaNiO5, in detail, as a…
Multiferroicity and magneto-electric effect in GdBaNiO
S. Chowki, Tathamay Basu, K. Singh +2
We report the observation of electric polarization in the magnetically ordered state of the Haldane chain compound, GdBaNiO, with strongly correlated magnetic and dielectri…
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.…
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 +5
We report that the spin-chain compound Dy2BaNiO5 recently proven to exhibit magnetoelectric coupling below its Neel temperature (T_N) of 58 K, exhibits strong frequency-dependent b…
Isothermal magnetic entropy behavior in Tb5Si3: Sign reversal and non-monotonic variation with temperature, and implications
Niharika Mohapatraa, Sitikantha D. Das, K. Mukherjee +1
The magnetic entropy change (\DeltaS), a measure of the magnetocaloric effect, in Tb5Si3, a compound exhibiting unusual positive magnetoresistance following a magnetic-field-induce…
