Nuclear quadrupole interaction and zero first-order Zeeman transitions of Er in CaWO
Lewin Marsh, Yikai Yang, Cesare Mattiroli +5
We report microwave spectroscopy of Er doped in CaWO which reveals the hyperfine splitting of the erbium electronic ground state (, =15/2)…

Evidence of rotational and tilting disorder of ReO6 octahedra in single crystals of a 5d1 double perovskite Ba2CaReO6
Alasdair Nicholls, Jian-Rui Soh, Yikai Yang +4
We present results of an experimental study on single crystals of a 5d1 double perovskite Ba2CaReO6. Magnetization measurements reveal a weak splitting between zero-field-cooled an…

Cavity-Magnon-Polariton spectroscopy of strongly hybridized electro-nuclear spin excitations in LiHoF4
Yikai Yang, Peter Babkevich, Richard Gaal +2
We first present a formalism that incorporates the input-output formalism and the linear response theory to employ cavity-magnon-polariton coupling as a spectroscopic tool for inve…
