Epitaxial SrIrO3 and CaIrO3 thin films on STO(001) substrates crystallize in the perovskite structure and both display paramagnetic and semimetallic behavior. We successfully synthesized epitaxially strained thin films of the substitution series CaxSr1-xIrO3. A non-monotonic evolution of the out-of-plane lattice parameter is found, which for low x increases with respect to that for pure SrIrO3. Interestingly, this strained state for x>0.1 is accompanied by the occurrence of an anomalous Hall effect contribution below 50 K, which suggests the emergence of ferromagnetism. However, the ferromagnetic signal could not yet be confirmed by bulk magnetization measurements probably due to the small magnetic moment of the Iridium atoms. We propose XMCD measurements to investigate the Ir ferromagnetism and characterize the strain-induced phase in CaxSr1-xIrO3 for few selected concentrations x.
