Probing low-energy hyperbolic polaritons in van der Waals crystals with an electron microscope
Alexander A. Govyadinov, Andrea Konečná, Andrey Chuvilin +8
Van der Waals (vdW) materials exhibit intriguing structural, electronic and photonic properties. Electron Energy Loss Spectroscopy (EELS) within Scanning Transmission Electron Micr…
Tunable sign change of spin Hall magnetoresistance in Pt/NiO/YIG structures
Dazhi Hou, Zhiyong Qiu, Joseph Barker +7
Spin Hall magnetoresistance (SMR) has been investigated in Pt/NiO/YIG structures in a wide range of temperature and NiO thickness. The SMR shows a negative sign below a temperature…
Competing effects at Pt/YIG interfaces: spin Hall magnetoresistance, magnon excitations and magnetic frustration
Saül Vélez, Amilcar Bedoya-Pinto, Wenjing Yan +2
We study the spin Hall magnetoresistance (SMR) and the magnon spin transport (MST) in Pt/Y3Fe5O12(YIG)-based devices with intentionally modified interfaces. Our measurements show t…
Ultra-confined acoustic THz graphene plasmons revealed by photocurrent nanoscopy
Pablo Alonso-Gonzalez, Alexey Y. Nikitin, Yuanda Gao +14
Terahertz (THz) fields are widely applied for sensing, communication and quality control. In future applications, they could be efficiently confined, enhanced and manipulated - wel…
