Coupled phase transitions in crystalline solids with extreme chemical disorder
Subha Dey, Rukma Nevgi, Suresh Chandra Joshi +13
Structural phase transitions often couple to magnetic and electronic degrees of freedom, enabling emergent phenomena in solids. In high-entropy oxides (HEOs), which typically stabi…
Extreme disorder in crystalline perovskite oxide: a new paradigm in quantum materials research
Srimanta Middey, Nandana Bhattacharya, Rukma Nevgi +2
Perovskite oxides (O) have long been central to the advancement of modern condensed matter physics, owing to their rich and tunable electronic and magnetic properties. The…
Local structural distortions drive magnetic molecular field in compositionally complex spinel oxide
Rukma Nevgi, Subha Dey, Nandana Bhattacharya +8
Understanding how local distortions determine the functional properties of high entropy materials, containing five or more elements at a crystallographic site, is an open challenge…
Strain glass versus antisite disorder induced ferromagnetic state in Fe doped Ni-Mn-In Heusler martensites
Rukma Nevgi, K. R. Priolkar, Mehmet Acet
Fe doping in NiMnIn results in suppression of the martensitic phase via two contrasting routes. In NiMnFeIn, the martensitic phase i…
