Restructuring disorder: Transformation from the antiferromagnetic order in Fe2VSi to the ferromagnetic state in FeRuVSi by substitution of a non-magnetic element
Shuvankar Gupta, Sudip Chakraborty, Celine Barreteau +4
The delicate nature of the half-metallic ferromagnetic (HMF) property in Heusler alloys is often compromised by inherent structural disorder within the systems. Fe2VSi is a prime e…
Randomness in atomic disorder and consequent squandering of spin-polarization in a ferromagnetically fragile quaternary Heusler alloy FeRuCrSi
Shuvankar Gupta, Sudip Chakraborty, Vidha Bhasin +7
RuFeCrSi ( 0 x 1) system is theoretically predicted to be one of the very few known examples of robust half-metallic ferromagnet with 100\% spin polarization. Si…
Large saturation moment and high ferromagnetic transition temperature in a structurally disordered inverse Heusler alloy Fe2RuGe
Sudip Chakraborty, Shuvankar Gupta, Vidha Bhasin +10
We report the successful synthesis of a new 4 based polycrystalline inverse Heusler alloy FeRuGe by an arc melting process and have studied in detail its structural, magneti…
4d-element induced improvement of structural disorder and development of weakly re-entrant spin-glass behaviour in NiRuMnSn
Shuvankar Gupta, Sudip Chakraborty, Vidha Bhasin +12
The pursuit of efficient spin-polarization in quaternary Heusler alloys with the general formula (where X, , and Y are transition metals and Z is a p-block element), ha…
Magnetic, structural and magnetocaloric properties of YGdFeH hydrides
V. Paul-Boncour, K. Provost, T. Mazet +3
At 300 K, YGdFeH hydrides crystallize sequentially with increasing H concentration in various structures related to a lowering of the cubic MgCu t…
Phase diagram and order-disorder transitions in YGdFeH hydrides (x 2.9)
V. Paul-Boncour, K. Provost, E. Alleno +3
YGdFe, which crystallizes in a C15 cubic structure, can absorb up to 5 H/f.u. and its pressure-composition isotherm displays a multiplateau behavior related t…
On the structure and electronic properties of FeVWAl thin films
E. Alleno, A. Berche, J. -C. Crivello +2
A very large thermoelectric figure of merit ZT = 6 at 380 K has recently been reported in FeVWAl under thin-film form (Hinterleitner et al., Nature 576 (2019) 8…
Optimization of criteria for an efficient screening of new thermoelectric compounds: the TiNiSi structure type as a case-study
Celine Barreteau, Jean-Claude Crivello, Jean-Marc Joubert +1
High-throughput calculations are a very promising tool for screening a large number of compounds in order to discover new useful materials. Ternary intermetallic are thus investiga…
Looking for new thermoelectric materials among the TMX intermetallics using high-throughput calculations
Celine Barreteau, Jean-Claude Crivello, Jean-Marc Joubert +1
Within 4 different crystal structures, 2280 ternary intermetallic configurations have been investigated via high-throughput density functional theory calculations in order to disco…
