Interplay of Valley, Orbital, Spin, and Layer Degrees of Freedom in TaCS MXene
Kunal Dutta, Anupam Mondal, Sayantika Bhowal +2
We show that the MXene TaCS provides an excellent platform for hosting multiple coupled degrees of freedom, viz., valley, spin, orbital, and layer. The interplay among thes…
Non-relativistic ferromagnetotriakontadipolar order and spin splitting in hematite
X. H. Verbeek, D. Voderholzer, S. Schären +3
We show that hematite, -FeO, below its Morin transition, has a ferroic ordering of rank-5 magnetic triakontadipoles on the Fe ions. In the absence of spin-orbit coupling…
GdAlSi: An antiferromagnetic topological Weyl semimetal with non-relativistic spin splitting
Jadupati Nag, Bishal Das, Sayantika Bhowal +9
Spintronics has emerged as a viable alternative to traditional electronics based technologies in the past few decades. While on one hand, the discovery of topological phases of mat…
Magnetic octupoles as the order parameter for unconventional antiferromagnetism
Sayantika Bhowal, Nicola A. Spaldin
We show that time-reversal symmetry broken, centrosymmetric antiferromagnets with nonrelativistic spin-splitting are conveniently described in terms of the ferroic ordering of magn…
The interplay between structural, magnetic and electronic states in the pyrochlore iridate Eu2Ir2O7
Manjil Das, Sayantika Bhowal, Jhuma Sannigrahi +8
We address the concomitant metal-insulator transition (MIT) and antiferromagnetic ordering in the novel pyrochlore iridate Eu2Ir2O7 by combining x-ray absorption spectroscopy, x-ra…
SrLiIrO: a potential quantum spin liquid candidate in the one dimensional iridate family
Abhisek Bandyopadhyay, A. Chakraborty, S. Bhowal +8
Spin-orbit coupling (SOC) offers a large variety of novel and extraordinary magnetic and electronic properties in otherwise `ordinary pool' of heavy ion oxides. Here we present a d…
