Abstract: Centimeter-sized single crystals of Sr1.5La0.5RhO4 were grown by the floating zone method at oxygen pressures of 20 bar. The quality of our single crystals was confirmed by x-ray Laue, powder and single crystal x-ray diffraction, neutron and x-ray absorbtion spectroscopy measurements. At ∼50% electron doping we observe RhO3 octahedral rotations of ∼8.2∘ within the octahedral basal plane which are incompatible with space group I4/mmm. Our single crystal was further characterized by susceptibility, electrical transport, and, finally, specific heat measurements showing a temperature-dependent Debye temperature.
