Impact of disorder in Nd-based pyrochlore magnets
Mélanie Léger, Florianne Vayer, Monica Ciomaga Hatnean +11
We study the stability of the antiferromagnetic all-in--all-out state observed in dipolar-octupolar pyrochlores that have neodymium as the magnetic species. Different types of diso…
Thermoelectric properties of high-entropy wolframite oxide: (CoCuNiFeZn)GaWO
Ashutosh Kumar, Adrien Moll, Mouhamad Navid Mouhamadsiradjoudine +3
In this report, the synthesis of high-entropy wolframite oxide (CoCuNiFeZn)GaWO through standard solid-state route followed by spark plasma sintering (SPS) and thei…
Long-range magnetic ordering in rocksalt-type high-entropy oxides
Marco Polo Jimenez-Segura, Tomohiro Takayama, David Bérardan +4
We report the magnetic properties of MgCoNiCuZnO, a high-entropy oxide with rocksalt structure, and the influence of substitutions on these…
The role of ionized impurity scattering on the thermoelectric performances of rock salt AgPbmSnSe2+m
Lin Pan, Sunanda Mitra, Li-Dong Zhao +4
We report on the successful synthesis and on the properties of polycrystalline AgPbmSnSe2+m (m = ++++, 100, 50, 25) samples with a rock salt structure. Between 160 K and 400 K, the…
Colossal dielectric constant in high entropy oxides
David Berardan, Sylvain Franger, Diana Dragoe +2
Entropic contributions to the stability of solids are very well understood and the mixing entropy has been used for forming various solids, for instance such as inverse spinels. A…
Evidence of structural phase transition in superconducting SmFeAsO_(1-x)F_x from 19^F NMR
M. Majumder, K. Ghoshray, C. Mazumdar +4
We report the resistivity, magnetization and 19^F NMR results in polycrystalline sample of SmFeAsO_(0.86)F_(0.14). The resistivity and the magnetization data show a sharp drop at 4…
Electronic phase diagram of NdFe1-xRhxAsO
David Berardan, Lidong Zhao, Loreynne Pinsard-Gaudart +1
We report on the electrical resistivity, thermoelectric power and electronic phase diagram of rhodium-doped NdFeAsO. Rhodium doping suppresses the structural phase transition and s…
Large Seebeck coefficients in Iron-oxypnictides : a new route towards n-type thermoelectric materials
Loreynne Pinsard-Gaudart, David Berardan, Julien Bobroff +1
The iron-oxypnictide compounds, recently reported as a new class of superconductors when appropriately doped, exhibit large Seebeck coefficients, of the order of -100 microV/K, whi…
