Giant Exfoliation Induced Magnetic Coercivity in FeGaTe
Lingrui Mei, PeiYu Cai, Sang-Eon Lee +6
Permanent magnets with strong anisotropy and high coercivity underpin modern information and energy technologies, yet rare-earth-free alternatives remain limited. Here, we show tha…
Tunable Polariton Canalization in Natural van der Waals Oxide
H. Shiravi, W. Zheng, D. A. Rhodes +3
Hyperbolic phonon polaritons (HPPs) are coupled oscillations of anisotropic lattice vibrations and electromagnetic fields that confine the latter to the nanoscale, enabling novel n…
Topological Hall Effect in Antiferromagnetic Co doped FeGaTe
Shyam Raj Karullithodi, Yeonkyu Lee, Vadym Kulichenko +8
FeGaTe is van der Waals (vdW) ferromagnet with a Curie temperature ranging from 350 K to 380 K, followed upon cooling by a ferrimagnetic transition near room temperat…
Charge dynamics in the Weyl semimetals NbIrTe and TaIrTe under pressure: Signatures of an electronic phase transition
M. Lamp, J. Ebad-Allah, A. Chmeruk +7
A high-pressure investigation of the Weyl semimetals NbIrTe and TaIrTe is presented, using infrared spectroscopy supplemented by density functional theory calculations. The…
Charge density wave in a band insulator
Md Shafayat Hossain, Wenhao Liu, Yuqi Zhang +20
Charge density wave (CDW) implies a periodic modulation of the charge density. Typically observed in metallic systems, CDWs arise from Fermi surface instabilities, resulting in the…
High magnetic field response of superconductivity dome in quantum artificial High Tc superlattices with variable geometry
Gaetano Campi, Andrea Alimenti, Sang-Eon Lee +5
It is known that cuprate artificial high Tc superlattices (AHTS) with period d, composed of quantum wells confining interface space charge in stoichiometric Mott insulator layers (…
