Query: Kitaev Magnetism and Fractionalized Excitations in Double Perovskite
  Sm2ZnIrO6   The quest for Kitaev spin liquids in particular three dimensional solids is
long sought goal in condensed matter physics, as these states may give rise to
exotic new types of quasi-particle excitations carrying fractional quantum
numbers namely Majorana Fermionic excitations. Here we report the experimental
signature of this characteristic feature of the Kitaev spin liquid via Raman
measurements. Sm2ZnIrO6 is a strongly spin orbit coupled Mott insulator, where
Jeff = 1/2 controls the physics, which provide striking evidence for this
characteristic feature of the Kitaev spin liquid. As the temperature is
lowered, we find that the spin excitations form a continuum in contrast to the
conventional sharp modes expected in ordered antiferromagnets. Our observation
of a broad magnetic continuum and anomalous renormalization of the phonon
self-energy parameters evidence the existence of Majorana fermions from spin
fractionalization in double perovskites structure as theoretically conjectured
in a Kitaev-Heisenberg geometrically frustrated double perovskite systems.
