Electron paramagnetic resonance of Dy-doped CaWO: spin Hamiltonian, crystal-field analysis, and linear electric field effect
Achuthan Manoj Kumar, Larissa Aboudem-Joumessi, Remy Dassonneville +6
We report an electron paramagnetic resonance (EPR) study of Dy in CaWO single crystals spanning dopant concentrations from 80~ppb to 247~ppm. The factors of the grou…

Strongly anisotropic non-Kramers electron spin as a quantum coherence probe of angular fluctuations
Achuthan Manoj Kumar, Remy Dassonneville, Guillaume Gerbaud +5
Strongly anisotropic non-Kramers rare-earth ions combine giant longitudinal g-factors with a vanishing transverse component imposed by time-reversal symmetry, a combination that ma…
