Unraveling the nature of magnetism of the 5${\mathbf{d}}^4$ double perovskite Ba${}_2$YIrO${}_6$

S. Fuchs, T. Dey, G. Aslan-Cansever +4

We report electron spin resonance (ESR) spectroscopy results on the double perovskite Ba${}_2$YIrO${}_6$. On general grounds, this material is expected to be nonmagnetic due to the str…
