“…The device is a lumped-element superconducting resonator, fabricated on a Czochralski-grown single crystal of Y 2 SiO 5 [24] doped with 10 ppm isotopically purified 145 Nd. The crystal was cut into a 5 mm×5 mm×460 µm chip along the principal dielectric axes (D 1 , D 2 , b) and a face perpendicular to b was polished for thin-film growth.…”

Yttrium orthosilicate (Y2SiO5, or YSO) has proved to be a convenient host for rare-earth ions used in demonstrations of microwave quantum memories and optical memories with microwave interfaces, and shows promise for coherent microwave-optical conversion owing to its favourable optical and spin properties. The strong coupling required by such microwave applications could be achieved using superconducting resonators patterned directly on Y2SiO5, and hence we investigate here the use of Y2SiO5 as an alternative to sapphire or silicon substrates for superconducting hybrid device fabrication. A NbN resonator with frequency 6.008 GHz and low power quality factor Q ≈ 400 000 was fabricated on a Y2SiO5 substrate doped with isotopically enriched 145 Nd. Measurements of dielectric loss yield a loss-tangent tan δ = 4 × 10 −6 , comparable to sapphire. Electron spin resonance (ESR) measurements performed using the resonator show the characteristic angular dependence expected from the anisotropic 145 Nd spin, and the coupling strength between resonator and electron spins is in the high cooperativity regime (C = 30). These results demonstrate Y2SiO5 as an excellent substrate for low-loss, high-Q microwave resonators, especially in applications for coupling to optically-accessible rare earth spins.

“…Shoudu Zhang et al had grown the undoped YSO single crystal by the Czochralski technique [8], but they didn't further study the spectral properties of the crystals. The color centers that are deleterious to spectral properties would be produced after irradiation, so it is very important that crystals possess outstanding irradiation properties as optical materials.…”

The absorption spectra of undoped Y 2 SiO 5 crystals were studied before and after γ-irradiation. After γ-irradiation, the additional absorption peaks at 260-270 and 320nm were observed in as-grown and H 2 -annealed Y 2 SiO 5 crystal, but it did not occur in air-annealed Y 2 SiO 5 crystal. These absorption peaks were attributed to F color centers and O -hole centers, respectively. Owing to more oxygen vacancies and color centers in H 2 -annealed Y 2 SiO 5 crystal than that in as-grown Y 2 SiO 5 crystal after γ-irradiation, the additional absorption peaks were more intense in the former than that in the latter. With the irradiation dose increasing from 20 to 220kGy, the intensity of additional absorption peaks increased.
