Researchers from Nanjing University of Science and Technology, led by Prof. Erjun Kan and Assoc. Prof. Yi Wan, together with Prof. Kaiyou Wang’s team at the Institute of Semiconductors, Chinese Academy of Sciences, has achieved a breakthrough in the study of two-dimensional (2D) ferromagnetic semiconductors. Using the CIQTEK Scanning NV Microscope (SNVM), the team successfully demonstrated room-temperature ferromagnetism in the semiconducting material MnS₂. The findings were published in the Journal of the American Chemical Society (JACS) under the title “Experimental Evidence of Room-Temperature Ferromagnetism in Semiconducting MnS₂.”   https://pubs.acs.org/doi/10.1021/jacs.5c10107   Pioneering Discovery in 2D Ferromagnetic Semiconductors The discovery of 2D ferromagnetic semiconductors has raised great expectations for advancing Moore’s Law and spintronics in memory and computation. However, most explored 2D ferromagnetic semiconductors exhibit Curie temperatures far below room temperature. Despite theoretical predictions of many potential room-temperature 2D ferromagnetic materials, the experimental synthesis of ordered and stable metastable structures remains a formidable challenge. In this study, the researchers developed a template-assisted chemical vapor deposition (CVD) method to synthesize layered MnS₂ microstructures within a ReS₂ template. High-resolution atomic characterizations revealed that the monolayer MnS₂ microstructure crystallized well in a distorted T-phase. The optical bandgap and temperature-dependent carrier mobility confirmed its semiconducting nature. By combining vibrating sample magnetometry (VSM), electrical transport measurements, and micro-magnetic imaging using CIQTEK SNVM, the team provided solid experimental evidence of room-temperature ferromagnetism in MnS₂. Electrical transport measurements also revealed an anomalous Hall resistance component in the monolayer samples. Theoretical calculations further indicated that this ferromagnetism originates from short-range Mn–Mn interactions. This work not only confirms the intrinsic room-temperature ferromagnetism of layered MnS₂ but also proposes an innovative approach for the growth of metastable functional 2D materials.     Two Key Breakthroughs Intrinsic Room-Temperature Ferromagnetism in MnS₂ Monolayers:The study experimentally demonstrates intrinsic room-temperature ferromagnetism in semiconducting MnS₂, resolving the long-standing conflict between semiconductivity and magnetism. Template-Assisted CVD Strategy for Metastable Ferromagnetic Microstructures:The developed synthesis strategy enables scalable fabrication of metastable ferromagnetic microstructures. These advances establish MnS₂ as a model platform for 2D spintronics, offering a new pathway for engineering low-dimensional magnetic materials.   ChatGPT 说： Figure 1: Optical and Magnetic Measurements   Figure 2: Micro-Region Magnetic...

A research team led by Prof. Haomin Wang from the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, has achieved significant progress in studying the magnetism of zigzag graphene nanoribbons (zGNRs) using the CIQTEK Scanning NV Microscope (SNVM). Building on their previous research, the team fabricated oriented atomic grooves in hexagonal boron nitride (hBN) by pre-etching with metal nanoparticles and synthesized chiral-controlled graphene nanoribbons within these grooves through a vapor-phase catalytic CVD method. The resulting ~9 nm-wide zGNRs embedded in the hBN lattice exhibited intrinsic magnetic properties, which were directly confirmed experimentally for the first time using SNVM combined with magnetic transport measurements. This groundbreaking work lays a solid foundation for developing graphene-based spintronic devices. The study, titled “Signatures of magnetism in zigzag graphene nanoribbons embedded in a hexagonal boron nitride lattice”, was published in the renowned journal Nature Materials.   https://doi.org/10.1038/s41563-025-02317-4 Understanding Graphene Magnetism Graphene, as a unique two-dimensional material, exhibits p-orbital electron magnetism that differs fundamentally from the localized d/f orbital magnetism found in conventional materials. This distinction opens new directions for exploring carbon-based quantum magnetism. Zigzag graphene nanoribbons (zGNRs) are particularly promising for spintronic applications because of their predicted magnetic electronic states near the Fermi level. However, detecting zGNR magnetism through electrical transport measurements has remained highly challenging. The main difficulties include the limited length of bottom-up synthesized nanoribbons, which complicates device fabrication, and the chemically reactive edges that lead to instability or inhomogeneous doping. Furthermore, in narrow zGNRs, strong antiferromagnetic coupling between edge states makes it difficult to electrically detect magnetic signals. These challenges have hindered direct observation of intrinsic magnetism in zGNRs.   SNVM Reveals Magnetic Signals at Room Temperature Embedding zGNRs within an hBN lattice enhances edge stability and introduces built-in electric fields, providing an ideal environment for studying magnetism. Using CIQTEK’s room-temperature SNVM, the researchers directly visualized magnetic signals in zGNRs for the first time under ambient conditions.   Figure 1. Magnetic measurement of zGNRs embedded in a hexagonal boron nitride lattice using the Scanning NV Microscope   In electrical transport measurements, the ~9 nm-wide zGNR transistors demonstrated high conductivity and ballistic transport behavior. Under magnetic fields, the devices showed pronounced anisotropic magnetoresistance, with resistance changes up to 175 Ω and a magnetoresistance ratio of approximately 1.3% at 4 K, which persisted up to 350 K.
