Magnetic excitations in a three-orbital model for the strongly spin-orbit coupled iridates: Effect of mixing between the J=1/2 and 3/2 sectors

Shubhajyoti Mohapatra, Jeroen van den Brink, Avinash Singh

A three-orbital-model approach for studying spin wave excitations in the strongly spin-orbit coupled layered perovskite iridates is presented which provides a unified description o…

Growth, microstructure and thermal transformation behaviour of epitaxial Ni-Ti films

Sandra Kauffmann-Weiss, Sandra Hahn, Carmen Weigelt +3

Epitaxial films have the potential to be used as model systems for fundamental investigations on the martensitic transformation in binary NiTi. In this paper, we discuss growth of…

Covalency and vibronic couplings make a nonmagnetic j=3/2 ion magnetic

Lei Xu, Nikolay A. Bogdanov, Andrew Princep +3

For 4 and 5 spin-orbit-coupled electron configurations, the notion of nonmagnetic j=3/2 quartet ground state discussed in classical textbooks is at odds with the observed…

Ba2NiOsO6: A Dirac-Mott insulator with ferromagnetism near 100 K

Hai L. Feng, Stuart Calder, Madhav Prasad Ghimire +14

The ferromagnetic semiconductor Ba2NiOsO6 (Tmag ~100 K) was synthesized at 6 GPa and 1500 °C. It crystallizes into a double perovskite structure [Fm-3m; a = 8.0428(1) Å], where the…

Role of magnetic dopants in the phase diagram of Sm1111 pnictides: The Mn case

G. Lamura, T. Shiroka, S. Bordignon +12

The deliberate insertion of magnetic Mn dopants in the Fe sites of the optimally-doped SmFeAsO0.88-F0.12 iron-based superconductor can modify in a controlled way its electronic pro…

Cross-over from an incommensurate singlet spiral state with a vanishingly small spin-gap to a valence bond solid state in dimerized frustrated ferromagnetic spin-chains

Cliò Efthimia Agrapidis, Stefan-Ludwig Drechsler, Jeroen van den Brink +1

Motivated by the magnetic properties of the spin-chain compounds LiCuSbOLiSbCuO and RbCuMoO, we study the ground state of the Heisenberg chain wi…
