Transparent magneto‐optical Ho2O3 ceramics were successfully prepared with an in‐line transmittance of ~73% at the wavelength of 1000 nm (~90% of the theoretical transmittance of Ho2O3 single crystal) and an average grain size of ~28 μm. The ceramics were fabricated using sulfate‐exchanged nitrate‐t...
