Description
The Ba$_3$MIr$_2$O$_9$ family offers a tremendous playground to study the influence of spin orbit coupling (SOC) in the stabilization of a spin liquid ground state. We present here the zero field $\mu$SR study of the $J=1/2$ compounds (M=Y,Sc,In) synthesized in the 6H lattice.
For the Y and Sc ones we found an homogeneous ordered ground state, with transitions at 4.5 K and 10 K respectively, as expected. Interestingly, for the In one, we found no sign of frozen magnetism down to 20 mK which could be the sign of a spin liquid ground state. Our study then rises questions about the different interactions in those compounds.
