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…
Positive and negative pressure effects on the magnetic ordering and the Kondo effect in the compound Ce2RhSi3
T. Nakano, Kausik Sengupta, Sudhindra Rayaprol +3
The competition between magnetic ordering and the Kondo effect in Ce2RhSi3, ordering antiferromagnetically at 7 K, is investigated by the measurements of magnetization, heat capaci…
Evidence for strong 5d electron correlations and electron-magnon coupling in a pyrochlore, Y2Ir2O7
R. S. Singh, V. R. R. Medicherla, Kalobaran Maiti +1
We report the observation of an unusual behavior of highly extended 5d electrons in Y2Ir2O7 belonging to pyrochlore family of great current interest using high resolution photoemis…
