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…
A first-order magnetic phase transition near 15 K with novel magnetic-field-induced effects in Er5Si3
Niharika Mohapatra, K. Mukherjee, Kartik K. Iyer +1
We present magnetic characterization of a binary rare-earth intermetallic compound Er5Si3, crystallizing in Mn5Si3-type hexagonal structure, through magnetization, heat-capacity, e…
Magnetic Anomalies in a New Manganocuprate Gd3Ba2Mn2Cu2O12
Sudhindra Rayaprol, Kiran Singh, N. K. Gaur +3
The manganocuprate compound Gd3Ba2Mn2Cu2O12 (Gd-3222) has been synthesized by conventional solid state reaction method and its magnetic behavior has been studied by dc and ac magne…
Magnetic phase transition and magnetocaloric effect in PrCo9Si4 and NdCo9Si4
Niharika Mohapatra, E. V. Sampathkumaran
The compounds, PrCo9Si4 and NdCo9Si4, have been recently reported to exhibit first-order ferromagnetic transitions near 24 K. We have subjected this compound for further characteri…
