Field-induced first-order magnetic phase transition in an intermetallic compound, Nd7Rh3: Evidence for kinetic-hindrance, phase co-existence and percolative conduction
Kausik Sengupta, E. V. Sampathkumaran
The compound, Nd7Rh3, crystallizing in Th7Fe3-type hexagonal structure, was previously known to exhibit two magnetic transitions, one at 32 K and the other at 10 K (in zero magneti…
Magnetic behavior of EuCu2As2: Delicate balance between antiferromagnetic and ferromagnetic order
Kausik Sengupta, P. L. Paulose, E. V. Sampathkumaran +2
The Eu-based compound, EuCu2As2, crystallizing in the ThCr2Si2-type tetragonal structure, has been synthesized and its magnetic behavior has been investigated by magnetization (M),…
Large magnetoresistance and magnetocaloric effect above 70 K in Gd2Co2Al, Gd2Co2Ga and Gd7Rh3
Kausik Sengupta, Kartik K. Iyer, E. V. Sampathkumaran
The electrical resistivity, magnetization and heat-capacity behavior of the Gd-based compounds, Gd2Co2Al, Gd2Co2Ga and Gd7Rh3, ordering magnetically at TC= 78 K, TC= 76 K and TN= 1…
Negative chemical pressure effects induced by Y substitution for Ca on the exotic magnetic behavior of spin-chain compound, Ca3Co2O6
S. Rayaprol, E. V. Sampathkumaran
The magnetic behavior of a solid solution, Ca3-xYxCo2O6, based on an exotic spin-chain compound, Ca3Co2O6, crystallizing in K4CdCl6-derived rhombohedral structure is investigated.…
Origin of charge density wave formation in insulators from a high resolution photoemission study of BaIrO3
Kalobaran Maiti, Ravi Shankar Singh, V. R. R. Medicherla +2
We investigate the origin of charge density wave (CDW) formation in insulators by studying BaIrO3 using high resolution (1.4 meV) photoemission spectroscopy. The spectra reveal the…
