Charge ordering in Ir dimers in the ground state of Ba5AlIr2O11

Oleg Yazyev, Xingye Lu, Vamshi Mohan Katukuri, Thorsten Schmitt, Vladimir N. Strocov

It has been well established experimentally that the interplay of electronic correlations and spin-orbit interactions in Ir4+ and Ir5+ oxides results in insulating J(eff) = 1/2 and J(eff) = 0 ground states, respectively. However, in compounds where the str ...

Exchange Interactions Mediated by Nonmagnetic Cations in Double Perovskites

Oleg Yazyev, Henrik Moodysson Rønnow, Peter Babkevich, Vamshi Mohan Katukuri, Sami Juhani Vasala

Establishing the physical mechanism governing exchange interactions is fundamental for exploring exotic phases such as quantum spin liquids in real materials. In this Letter, we address exchange interactions in Sr2CuTexW1-xO6, a series of double perovskite ...

Magnetic Excitations and Electronic Interactions in Sr2CuTeO6: A Spin-1/2 Square Lattice Heisenberg Antiferromagnet

Oleg Yazyev, Henrik Moodysson Rønnow, Peter Babkevich, Vamshi Mohan Katukuri

Sr2CuTeO6 presents an opportunity for exploring low-dimensional magnetism on a square lattice of S = 1/2 Cu2+ ions. We employ ab initio multireference configuration interaction calculations to unravel the Cu2+ electronic structure and to evaluate exchange ...
