Magnetic anomalies in single crystalline ErPd2Si2
E. V. Sampathkumaran, Niharika Mohapatra, Kartik K Iyer +3
Considering certain interesting features in the previously reported 166Er Moessbauer effect and neutron diffraction data on the polycrystalline form of ErPd2Si2 crystallizing in Th…
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…
Large magnetocaloric effect in Gd4Co3
Niharika Mohapatra, Kartik K Iyer, E. V. Sampathkumaran
We report a large entropy change (DeltaS) below 300 K, peaking near TC= 220 K, due to isothermal change of magnetic field, for Gd4Co3, with a refrigeration capacity higher than tha…
Geometrically frustrated magnetic behavior of Sr3NiRhO6 and Sr3NiPtO6
Niharika Mohapatra, Kartik K Iyer, Sudhindra Rayaprol +1
The results of ac and dc magnetic susceptibility isothermal magnetization and heat-capacity measurements as a function of temperature (T) are reported for Sr3NiRhO6 and Sr3NiPtO6 c…
Effect of a small disruption of the Ca site on the geometrically frustrated magnetic behavior of Ca3CoRhO6
Niharika Mohapatra, E. V. Sampathkumaran
The compound, Ca3CoRhO6, containing magnetic Co-Rh chains intervened by Ca ions, has been known to be one of the few exhibiting partially disordered antiferromagnetic structure (PD…
Magnetic anomalies in a spin-chain compound, Sr3CuRhO6: Griffiths-phase-like behavior of magnetic susceptibility
E. V. Sampathkumaran, Niharika Mohapatra, Sudhindra Rayaprol +1
We report the results of ac and dc magnetic susceptibility (chi), heat-capacity (C), isothermal magnetization and isothermal remanent magnetization measurements on the compound, Sr…
