Unraveling the nature of magnetism of the 5 double perovskite BaYIrO
S. Fuchs, T. Dey, G. Aslan-Cansever +4
We report electron spin resonance (ESR) spectroscopy results on the double perovskite BaYIrO. On general grounds, this material is expected to be nonmagnetic due to the str…

Orbiton-Phonon coupling in Ir5+(5d4) double perovskite Ba2YIrO6
Birender Singh, G. A. Cansever, T. Dey +4
Ba2YIrO6, a Mott insulator, with four valence electrons in Ir5+ d-shell (5d4) is supposed to be non-magnetic, with Jeff = 0, within the atomic physics picture. However, recent sugg…

Ba2YIrO6: A cubic double perovskite material with Ir5+ ions
T. Dey, A. Maljuk, D. V. Efremov +13
Materials with a 5d4 electronic configuration are generally considered to have a nonmagnetic ground state (J=0). Interestingly, Sr2YIrO6 (Ir5+ having 5d4 electronic configuration)…
