“…After submission of our manuscript, we found a recently published paper [ 53 ] in which they reported the co-existence of mixed magnetic phases in Ti 3 C 2 T x MXene obtained from the selective etching of Ti 3 SiC 2 MAX phase. Although they do not show M vs. H curves with sufficient resolution to observe the hysteresis loops, they suggest that their data reveal FM and diamagnetic phases.…”

Two-dimensional materials based on transition metal carbides have been intensively studied due to their unique properties including metallic conductivity, hydrophilicity and structural diversity and have shown a great potential in several applications, for example, energy storage, sensing and optoelectronics. While MXenes based on magnetic transition elements show interesting magnetic properties, not much is known about the magnetic properties of titanium-based MXenes. Here, we measured the magnetic properties of Ti3C2Tx MXenes synthesized by different chemical etching conditions such as etching temperature and time. Our magnetic measurements were performed in a superconducting quantum interference device (SQUID) vibrating sample. These data suggest that there is a paramagnetic-antiferromagnetic (PM-AFM) phase transition and the transition temperature depends on the synthesis procedure of MXenes. Our observation indicates that the magnetic properties of these MXenes can be tuned by the extent of chemical etching, which can be beneficial for the design of MXenes-based spintronic devices.

Ceramics is one of the oldest materials prepared and used by human beings. Ancient ancestors started to make pottery by forming and burning clay since the earliest civilizations. Ancient people started to fabricate burnt claywares since %6500 B.C., and clayware as a commercial product was available by %4000 B.C. [1] In modern society, as one of the largest branches in material family, ceramics have been developed and used in almost every fields of human beings' lives. In some senses, ceramics and metals possess complementary properties; generally, ceramics show the advantages of high strength, high hardness, high chemical stability, high wear resistance, whereas ceramics typically show intrinsic brittleness and poor plasticity due to their covalent and/or ionic chemical bonding; metals have good plasticity, high toughness, and high thermal and electronic conductivity; however, they typically show lower chemical stability and lower hardness than ceramics. It would be marvelous for a material to combine the properties of ceramics and metals. MAX phases are the materials that meet the challenge.MAX phases are a family of nanolaminate ternary nitrides and carbides, which were first discovered by Nowotny and his colleagues in Vienna. [2] In the beginning, MAX phases have a general formula of M nþ1 AX n (n ¼ 1-3), where M is a transition metal, A is an element from group A, and X is either carbon or nitrogen. The n value could be 1, 2, or 3, and the phases are named as 211, 312, and 413 MAX phases, respectively. These MAX phases show a hexagonal crystal structure (P63/mmc), consisting of M 6 X octahedra separated by A atomic layers. [3] M─X bonds in M 6 X octahedra are strong covalent bonds, whereas the M─A bonds between M 6 X and A atomic layer are much weaker, especially in shear. This unique bonding structure is analogous to graphite, and it is the special bonding structure that endows MAX phases properties of both ceramics and metals. On the one hand, MAX phases are stiff, lightweight, chemically stable, and oxidation resistant, which are the features of ceramics; on the other hand, they exhibit good electric and thermal conductivity as well as excellent machinability and damage tolerance, which are the features of metals.Unfortunately, MAX phases had not attracted enough attention in both academia and industry until 1996 when Barsoum et al. [4] synthesized and characterized Ti 3 SiC 2 . Ever since then, material researchers become more interested in this material. [5] In the past two decades, many MAX phases have been synthesized and tested to show highly unusual properties, [6] which will be discussed with detail in the following sections. The intensive extent of the researches on MAX phases can be demonstrated by the published papers (Figure 1). A remarkable jump can be observed between 1998 and 1999, and after that, the number of published papers increases steadily, reaching as high as 980 papers in 2019 (Figure 1a). From another aspect, the citation of the milestone paper published by Barsoum [4] also signific...

“…In the best-optimized sample, ferromagnetic and diamagnetic phases coexist because a small quantity of silicon (Si) is present in the MXene sample in the form of the SiC phase, which is employed to induce the diamagnetic phase in the MXene sample. [12] A thorough investigation of the effects of electric poling, frequency, the effect of a static magnetic field on ferroelectricity, and other variables at room temperature on the recently found ferroelectricity and multiferroicity in heated 2D Ti 3 C 2 Tx MXene has been conducted. [13] The precipitation of nanocrystals with a relatively wide size distribution is the result, though.…”

CoFe2O4, ZnFe2O4, NiFe2O4, Co0.5Ni0.5Fe2O4, Ni0.5Zn0.5Fe2O4, and Co0.5Zn0.5Fe2O4 are among the multicomponent ferrite nanoparticles that are created using the reverse microemulsion technique and a mixed surfactant. These nanoparticles are thoroughly characterized using techniques such as vibrating sample magnetometer (VSM), energy dispersive X‐ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FT‐IR), and X‐ray diffraction (XRD). All the nanoparticles display a cubic spinel crystal structure, according to the X‐ray investigation. As the concentration of zinc increases, there is a noticeable rise in the lattice constant because the size of Zn+2 is more than Co+2. This study also investigates the relationship between the magnetic characteristics of nanocrystals and their matching size, composition, and features.
