“…Once DyAG crystals were firstly discovered, it became a rare‐earth garnet of higher performance compared with Gd 3 Ga 5 O 12 (GGG) with scope for liquefying helium gas at around 15 K. Aside from this, DyAG crystals actually can be applied in many other fields, such as substrate for superconducting materials, magneto‐optical crystals, magnetostriction materials, and are even popular in studies of magnetic interactions of metal ions via the optical absorption and fluorescence spectra . In the past several decades, many works have been focused on the growth of large size DyAG single crystals . However, it remains a challenge technologically to grow crystals sized up to 50 mm in diameter using a Czochralski or Bridgman method.…”
