Surface plasmon resonances boost the transverse magneto-optical Kerr effect in a CoFeB slab covered by a subwavelength gold grating for highly sensitive detectors.

Herein, we have theoretically investigated the sensing performance-including enormous increase in the sensitivity and figure of merit (FOM)-of a magneto-optical surface plasmon resonance (MOSPR) sensor, which is based on the transverse magneto-optical Kerr effect (T-MOKE) in a ferromagnet coupled with a noble-metal grating. Specifically, we propose to use a CoFeB magnetic slab covered by a subwavelength, periodic gold grating configured as a magnetoplasmonic heterostructure. In such a device, sharp, Fano-like T-MOKE signals of high amplitude can be achieved due to the surface plasmon resonances (SPRs) excited in the presence of the gold grating, especially after optimizing the grating period.

Exfoliated Graphite Nanosheets Coating on Nano-grained SnO/LiTiO as a High-Performance Anode Material for Lithium-Ion Batteries.

The SnO/LiTiO/C compound was gained via hydrothermal, sintering, and ball milling methods. Nano-grained SnO/LiTiO are homogeneously wrapped in a sheet-like graphite. LiTiO possesses cyclic stability and superior rate capacity.
