“…The band structure of Bi 5 O 4 S 2.75 Cl differs from that of Sr 1‐x La x FBiS 2 and REO 1‐x F x BiS 2 (RE = La, Ce, Pr, and Nd), in which the element doping doesn't change the crystal structure and just lifts the Fermi level leaving only electron pockets near the Fermi level. [ 32–33 ] Furthermore, the TDOS (Figure 5d) of Bi 5 O 4 S 2.75 Cl at Fermi level increases much. In particular, the PDOS shows that Fermi level is on the peak position of the Bi1 6 p orbitals and S2 3 p orbitals, suggesting that the plane square lattice (Bi1‐S2) is dominant in the active superconducting BiS 3 layer.…”

“…Besides, the fat band (Figure S6b, Supporting Information) of Bi 5 O 4 S 3 Cl shows the hybridization between bismuth and sulfur atoms (S2) on the conduction band, which is consistent with that of LaOBiS 2 . [ 32 ] As depicted in Figure 5c, the topology of Fermi surface of Bi 5 O 4 S 2.75 Cl changes a lot and the Fermi level crosses both electron pockets and hole pockets in comparison with that of Bi 5 O 4 S 3 Cl. The band structure of Bi 5 O 4 S 2.75 Cl differs from that of Sr 1‐x La x FBiS 2 and REO 1‐x F x BiS 2 (RE = La, Ce, Pr, and Nd), in which the element doping doesn't change the crystal structure and just lifts the Fermi level leaving only electron pockets near the Fermi level.…”

The BiS2‐based layered superconductors with structures similar to those of cuprates and iron‐based superconductors have stimulated much research interest. Here, a new quaternary compound is reported, Bi5O4S3Cl, which crystalizes in a tetragonal structure with P4/mmm (No. 123) space group having alternately stacking unique BiS3 layers and Bi2O2 layers along the c‐axis with a Cl atom located at the center of the unit cell. A superconducting transition above 3 K is observed for both electrical transport and magnetic measurements. Hall resistivity measurements show its multiband character with a conduction dominated by electron‐like charge carriers. The first‐principles calculations exhibit that the semiconducting parent phase Bi5O4S3Cl becomes metallic when sulfur vacancies are introduced, which hints the origin of superconductivity in Bi5O4S3Cl. The findings will inspire the exploration of new BiS‐based superconductors.

Magnetic fluid (MF) is a novel kind of magneto-optical functional material that possesses diverse magneto-optical properties such as tunable refractive index, birefringence effect, dichroism effect, Faraday effect, field dependent transmission property and so on. It can serve as the magnetically sensitive material playing the key role in magnetic field sensors and magneto-optical devices. There were many reported photonic devices based on MF in the literatures. This thesis focuses on investigating the magneto-optical properties of MF for fiber optics applications. The thesis first reviewed the background knowledge including the MF, optical fibers and optical fiber interferometry. The physical origin of refractive index tunability and birefringence effect of MF are detailedly discussed in preparation for the works in the following Chapters. In the thesis, we have presented three kinds of MF-based magnetic field sensors. The first one is based on the birefringence effect of MF. The MF is inserted into an optical fiber Loyt-Sagnac interferometric configuration in the form of MF film. The sensitivity characteristics of this optical fiber Loyt-Sagnac interferometric configuration are theoretically analyzed and experimentally verified. Finally, a sensitivity of 59.2 pm/Oe is achieved by applying the conclusions drawn from the theoretical analysis to the proposed magnetic field sensing configuration. The second one is based on refractive index tunability of MF and the evanescent field of photonic crystal fiber with air-holes collapse. The evanescent light field interacts with the MF and translates the magnetic field strengths into optical signals. A Mach-Zehnder interferometric configuration formed by cascading two sections of v
