Second-Harmonic Imaging of Magnetic Domains in Thin Film Hematite
Holger Mirkes, Johannes Schmuck, Katharina Müller +7
Hematite is an antiferromagnetic oxide and candidate altermagnetic insulator whose Néel order reorients from an easy-axis to an easy-plane phase at the Morin transition. Interpret…
Elucidating magnetic structure with optical dopants: erbium-doped GdSiO
Luke S. Trainor, Masaya Hiraishi, J. -R. Soh +1
The narrowness of the optical transitions of rare-earth-ion dopants makes them highly sensitive probes of their environment. We measured the optical transitions Er dopants t…
Cavity-altered superconductivity
Itai Keren, Tatiana A. Webb, Shuai Zhang +30
Is it feasible to alter the ground state properties of a material by engineering its electromagnetic environment? Inspired by theoretical predictions, experimental realizations of…
Extrinsic nature of the polarization in hafnia ferroelectrics
Binayak Mukherjee, Natalya S. Fedorova, Jorge Ãñiguez-González
Hafnia and related fluorites defy our understanding of ferroelectricity, even if we restrict ourselves to the intrinsic properties of ideal crystals. Here we focus on a critical pu…
