Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

Advanced Materials, EarlyView.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Excitation Wavelength Dependent Luminescence Quantum Yields of Plasmonic Nanostructures

, 2016
We show that luminescence quantum yields of plasmonic nanostructures are dependent on the excitation wavelength. The quantum yields are higher when the excitation wavelength is blue-detuned and close to their surface plasmon resonant peak.CPCI-S ...
