Heavy Fermion superconductor CeCuSi under high pressure: multiprobing the valence crossover
G. Seyfarth, A. -S. Rüetschi, K. Sengupta +4
The first heavy fermion superconductor CeCuSi has not revealed all its striking mysteries yet. At high pressures, superconductivity is supposed to be mediated by valence fl…
Superconductivity in SnO: a Nonmagnetic Analog to Fe-based Superconductors?
M. K. Forthaus, K. Sengupta, O. Heyer +6
We found that under pressure SnO with alpha-PbO structure, the same structure as in many Fe-based superconductors, e.g. beta-FeSe, undergoes a transition to a superconducting state…
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…
An anomalous magnetic phase transition at 10 K in Nd7Rh3
Kausik Sengupta, E. V. Sampathkumaran
The compound, Nd7Rh3, crystallizing in Th7Fe3-type hexagonal structure, has been shown recently by us to exhibit a signature of magnetic phase-coexistence phenomenon below 10 K aft…
Magnetic and magnetoresistance behavior of Tb7Rh3, an intermetallic compound with a negative temperature coefficient of electrical resistivity in the paramagnetic state, and Paramagnetic Giant Magnetoresistance Phenomenon
Kausik Sengupta, Kartik K Iyer, E. V. Sampathkumaran
The results of dc magnetization, electrical and magnetoresistance and heat capacity measurements (2-300 K) on Tb7Rh3, crystallizing in Th7Fe3-type hexagonal structure, are reported…
Single-ion Kondo behavior of a novel Kondo lattice, CeNi9Si4
Kausik Sengupta, E. V. Sampathkumaran
The compound, CeNi9Si4 has been recently reported to be an unusual Kondo lattice with a large Ce-Ce separation, with a breakdown of Kadowaki-Woods relationship governing low temper…
