Strain-Induced Relaxor Multiferroicity at Room Temperature in Hexaferrite BaFe12O19 Thin Films
Yilin Evan Li, Harikrishnan KP, Sankalpa Hazra +19
Multiferroic materials that combine magnetic and electric order at room temperature are rare. Here, we demonstrate strain-induced room-temperature polar order in the ferrimagnetic…

Loss Mechanisms in Cryogenic Microwave Epitaxial AlN Resonators
Hemant Gulupalli, Navnil Choudhury, Jiacheng Xie +6
Epitaxial aluminum nitride (AlN) thin-film bulk acoustic resonators (FBARs) enable low loss filtering for future 6G systems. They also provide a compact approach for qubit sensing…

Improper Ferroelectricity at the Monolayer Limit
Yilin Evan Li, Harikrishnan KP, Haidong Lu +20
Ultrathin ferroelectric films with out-of-plane polarization and high Curie temperatures are key to miniaturizing electronic devices. Most ferroelectrics employed in devices are pr…
