Measurements were taken on a Quantum Design PPMS-9 using a 1 mA excitation current in magnetic fields between ± 1 T at temperatures from 350 K to 200 K. The Hall component of the transverse voltage V xy was obtained by extracting the odd function dependence of the transverse resistance with an applied magnetic field. For optical measurements, a Shimadzu Solid UV-Vis-IR 3700 spectrophotometer was used to measure the transmittance of the crystals over the range of 250 nm to 900 nm.
