Phase‐Change Hyperbolic Heterostructures for Nanopolaritonics: A Case Study of hBN/VO<sub>2</sub> Open
Unlike conventional plasmonic media, polaritonic van der Waals (vdW) materials hold promise for active control of light–matter interactions. The dispersion relations of elementary excitations such as phonons and plasmons can be tuned in la…

Insulator to metal transition induced by surface plasmon polaritons in VO<sub>2</sub>/Au thin films Open
We report on a new mechanism capable of inducing the insulator-metal transition (IMT) in VO2 via surface plasmon polaritons (SPP). Our theoretical model predicts that for a bilayer Au-VO2 sample an enhanced electromagnetic energy density a…

Spin-torque switching in large size nano-magnet with perpendicular magnetic fields Open
DC current induced magnetization reversal and magnetization oscillation was observed in 500 nm large size Co90Fe10/Cu/Ni80Fe20 pillars. A perpendicular external field enhanced the coercive field separation between the reference layer (Co90…
