Dielectric Properties of Single Crystal Calcium Tungstate
Elrina Hartman, Michael E Tobar, Ben T McAllister +3
This investigation employed microwave whispering gallery mode (WGM) analysis to characterize the dielectric properties of a cylindrical, single-crystal sample of calcium tungstate…
Conductivity Freeze-Out in Isotopically Pure Si-28 at milli-Kelvin Temperatures
Ben T. McAllister, Zijun C. Zhao, Jeremy F. Bourhill +4
Silicon is a key semiconducting material for electrical devices and hybrid quantum systems where low temperatures and zero-spin isotopic purity can enhance quantum coherence. Elect…
Low-Temperature Microwave Properties of Biaxial YAlO3
N. C. Carvalho, M. Goryachev, J. Krupka +2
Low-loss crystals with defects due to paramagnetic or rare earth impurity ions is a major area of investigation for quantum hybrid systems at both optical and microwave frequencies…
Multi-mode technique for the determination of the biaxial Y2SiO5 permittivity tensor from 300 to 6 Kelvin
N. C. Carvalho, J-M. Le Floch, J. Krupka +1
The Y2SiO5 (YSO) crystal is a dielectric material with biaxial anisotropy with known values of refractive index at optical frequencies. It is a well-known rare-earth (RE) host mate…
Evidence of Dilute Ferromagnetism in Rare-Earth doped YAG
W. G. Farr, M. Goryachev, J. M. le Floch +2
This work demonstrates strong coupling regime between an Erbium ion spin ensemble and microwave Hybrid Cavity-Whispering Gallery Modes in a Yttrium Aluminium Garnet dielectric crys…
