A series of square planar metalloporphyrins (M(TPP), TPP is 5,10,15,20-tetraphenylporphyrin and M(TPFPP), TPFPP is 5,10,15,20tetrapentafluorophenylporphyrin; M is Zn 2+ , Ni 2+ , Pd 2+ , or Pt 2+ ) with distinct meso-substituents were prepared, and their magneto-optical activity (MOA) was characterized by magnetic circular dichroism (MCD) and magnetooptical rotary dispersion spectroscopy (MORD; also known as Faraday rotation spectroscopy). MOA is crucial in the development of next-generation magneto-optical devices and quantum computing. The data show that the presence of meso-pentafluorophenyl substituents results in significant increase in MOA in comparison to the homologous phenyl group. Differences in the MOA of these metalloporphyrins are rationalized using the Gouterman fourorbital model and pave the way for rational design of improved and tailorable magneto-optical materials.

“…However, it has not stopped developing along with technological advances by adapting through the progression of materials and systems to the requirements of innovative applications. In high-performance laser devices, Faraday isolators are one of the important components that can prevent the frontend system from disturbance and damage caused by a backreflected beam [4]. Magneto-optical materials are thus widely studied as they are key elements of Faraday isolators [5].…”

Faraday isolators can prevent the front-end system from disturbance and damage caused by a back-reflected beam, so they are important elements in laser systems. As magneto-optical materials are the most important component in Faraday isolators, the studies on magneto-optical materials have attracted much attention these years. Tb 3 Al 5 O 12 (TAG) ceramics are considered to be one of the most promising magneto-optical materials for visible to near-infrared wavelength band application because of their outstanding comprehensive magneto-optical performance. However, the optical quality of TAG ceramics needs further optimization to meet the application requirements. In this work, high optical quality (Tb 1−x Y x ) 3 Al 5 O 12 (x = 0, 0.05, 0.1, 0.2, and 0.3) magneto-optical ceramics were fabricated successfully by solid-state reaction sintering combined with hot isostatic pressing (HIP) post-treatment. All the ceramics obtained showed a single garnet phase for different values of x in the range studied. The addition of Y 2 O 3 was found to suppress the secondary phase and improve optical quality significantly. The ceramic samples obtained had clear grain boundaries and possessed the inline transmittance values of 82.9% at 1064 nm and 82.2% at 633 nm, respectively. The Verdet constants of (Tb 1−x Y x ) 3 Al 5 O 12 ceramics with x = 0, 0.05, 0.1, 0.2, and 0.3 were −188.1, −175.4, −168.5, −143.0, and −119.9 rad/(T•m), respectively. The thermal conductivity of TAG ceramics was found to be 5.23 W/(m•K) at 25 ℃, and when 20% Y was substituted in place of Tb, the thermal conductivity decreased by only 9.4%.

“…With the development of the aerospace and defense industries, traditional silicon‐based ceramics have been proven insufficient in meeting the demand for high‐temperature structural materials 1–6 . As a novel structural material, SiBCN ceramics have recently gained considerable concern for their superior high‐temperature, oxidation, and creep resistance, in comparison to other silicon‐based ceramics (e.g., Si 3 N 4 ).…”

The impact of Zr addition on the solid sintering process of SiBCN multiphase ceramics was investigated under high temperatures. To gain deep insight, SiBCN‐Zr diffusion couple method (sample preparation at 1500–1800°C) was utilized in conjunction with first‐principles calculations. Significantly, the results demonstrated the formation of SiC and BN as well as ZrC/ZrB2 at the interface of the diffusion couples. Possible mechanisms have been analyzed and proposed. On the one hand, the extensive generations of defects are supposed to facilitate the formation of SiC and ZrC during the preparation of SiBCN amorphous powders. On the other hand, the presence of distinctive BN(C) structures in SiBCN hindered the formation of ZrB2, thus causing a delay in its formation. Through first‐principles calculations, remarkable variations in interatomic bonding strengths have been revealed among the different phases at the interface. Specifically, interfaces of ZrC/ZrB2 and SiC exhibit stronger bonding strengths compared to BN and SiC, implying that Zr, and its compounds may act as binding agents.
