Inelastic neutron scattering study on double perovskite Sr2TIrO6 (T = Ca, Sc, Y, Lu, Mg)
Abstract: Recent observation of AFM transition at 1.3 K in Sr2YIrO6 with Ir in 5+ valence state has motivated research interests in the double perovskite Sr2TIrO6. Usually Ir5+ with a non-degenerate singlet ground state is nonmagnetic in nature. The unusual magnetism in Sr2YIrO6 arising from Ir5+ has been argued to result from the presence of strong crystal electric field (CEF) on the Ir sites. A breakdown of spin-orbit coupling (SOC) driven ground state as a result of delicate competition between the SOC, local exchange interactions and CEF is the key to the observed unusual magnetism of Ir5+ in Sr2YIrO6. Since the CEF is at the heart of magnetism in Sr2TIrO6, the investigation of CEF and magnetic excitations in these compounds using inelastic neutron scattering is highly desired for a better insight to the unusual magnetic ground state. We therefore propose to carry out INS study on Sr2TIrO6.
