Large Anomalous and Topological Hall Effect and Nernst Effect in a Dirac Kagome Magnet Fe3Ge
Chunqiang Xu, Shuvankar Gupta, Hengxin Tan +9
The search for kagome magnets with unconventional magnetic and electronic properties has gained significant attention in recent years. We report the magnetic, electronic, and therm…
ErMnSn: A Promising Kagome Antiferromagnetic Candidate for Room-Temperature Nernst Effect-based thermoelectrics
Olajumoke Oluwatobiloba Emmanuel, Shuvankar Gupta, Xianglin Ke
The Nernst effect, the generation of a transverse electric voltage in the presence of longitudinal thermal gradient, has garnered significant attention in the realm of magnetic top…
Giant Nernst Angle in Self-Intercalated van der Waals Magnet CrTe
Shuvankar Gupta, Olajumoke Oluwatobiloba Emmanuel, Yasemin Ozbek +4
The discovery of two-dimensional van der Waals (vdW) magnetic materials has propelled advancements in technological devices. The Nernst effect, which generates a transverse electri…
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…
Comparative study of Kondo effect in Vanadium dichalcogenides VX (X=Se & Te)
Indrani Kar, Susanta Ghosh, Shuvankar Gupta +2
We report on the electrical transport, magnetotransport, and magnetic properties studies on the transition metal dichalcogenides VSe and VTe and draw a comprehensive compar…
Origin of magnetic ordering in half-Heusler RuMnGa
Sudip Chakraborty, Shuvankar Gupta, Santanu Pakhira +6
The half-Heusler alloy RuMnGa having valence electron count (VEC) 18 has recently been theoretically proposed to exhibit compensated ferrimagnetic (CFiM) character instead of the e…
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…
Experimental observation of spin glass state in highly disordered quaternary Heusler alloy FeRuMnGa
Shuvankar Gupta, Sudip Chakraborty, Santanu Pakhira +8
The realization of spin-glass (S-G) state in Heusler alloys is very rare despite the presence of inherent structural and elemental disorder in those compounds. Although a few half…
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…
