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…
Polar metals: Principles and Prospects
Sayantika Bhowal, Nicola A. Spaldin
We review the class of materials known as polar metals, in which polarity and metallicity coexist in the same phase. While the notion of polar metals was first invoked more than 50…
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…
Magnetoelectric classification of skyrmions
Sayantika Bhowal, Nicola A. Spaldin
We develop a general theory to classify magnetic skyrmions and related spin textures in terms of their magnetoelectric multipoles. Since magnetic skyrmions are now established in i…
Orbital Hall effect in bilayer transition metal dichalcogenides: From the intra-atomic approximation to the Bloch states orbital magnetic moment approach
Tarik P. Cysne, Sayantika Bhowal, Giovanni Vignale +1
Using an effective Dirac model, we study the orbital Hall effect (OHE) in bilayers of transition metal dichalcogenides with 2H stacking (2H-TMD). We use first-order perturbation th…
