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…
High spin-polarization in a disordered novel quaternary Heusler alloy FeMnVGa
Shuvankar Gupta, Sudip Chakraborty, Vidha Bhasin +10
In this work, we report the successful synthesis of a Fe-based novel half-metallic quaternary Heusler alloy FeMnVGa and its structural, magnetic and transport properties probed thr…
Coexisting structural disorder and robust spin-polarization in half-metallic FeMnVAl
Shuvankar Gupta, Sudip Chakraborty, Santanu Pakhira +6
Half-metallic ferromagnets (HMF) are on one of the most promising materials in the field of spintronics due to their unique band structure consisting of one spin sub-band having me…
A Detailed Investigation of the Onion Structure of Exchanged Coupled Magnetic Fe(3-delta)O4@CoFe2O4@Fe(3-delta)O4 Nanoparticles
Kevin Sartori, Anamaria Musat, Fadi Choueikani +7
Nanoparticles (NPs) which combine several magnetic phases offer wide perspectives for cutting edge applications because of the high modularity of their magnetic properties. Besides…
Coupled structural and magnetic properties of ferric fluoride nanostructures: part II, a Monte-Carlo Heisenberg study
B. Fongang, I. Labaye, J. -M. Greneche +2
We present a numerical study of the magnetic structure of nanostructured iron fluoride, using the Monte-Carlo-Metropolis simulated annealing technique and a classical Heisenberg Ha…
Coupled structural and magnetic properties of ferric fluoride nanostructures part I: a Metropolis atomistic study
B. Fongang, I. Labaye, S. Zekeng +2
A modified Metropolis atomistic simulation is proposed to model the structure of grain boundaries (GBs) and interfaces in ionic nanostructured systems and is applied to the magneti…
