Ba1.8Sr0.2Co2Fe11.9Pr0.1O22/Ti3C2Tx‐MXene composites are synthesized with the unique combination of magnetic and conducting components that enhance electromagnetic wave absorption. Ba1.8Sr0.2Co2Fe11.9Pr0.1O22, Ti3C2Tx‐MXene and their composites in a weight ratio of 100:0 (YM1), 75:25 (YM2) and 50:50 (YM3) are synthesized by sol–gel autocombustion, etching process, and mechanical blending, respectively. From the morphology of the composites, Ba1.8Sr0.2Co2Fe11.9Pr0.1O22 particles are confirmed to be well‐integrated with the Ti3C2Tx‐MXene, indicating that the Ba1.8Sr0.2Co2Fe11.9Pr0.1O22 particles are evenly distributed in the Ti3C2Tx‐MXene, leading to homogeneous composites. M–H loop exhibits a saturation magnetization and coercivity of 23.01 emu g−1, 14.87 emu g−1, 12.45 emu g−1, and 87.44 Oe, 94.06 Oe, 102.97 Oe for YM1, YM2, and YM3, respectively. The reflection losses for YM1, YM2, and YM3 are −8.88, −11.64, and −21.39 dB, respectively. The double‐resonance peaks contribute to two magnetic loss peaks in YM3 within a broad frequency range. The higher attenuation constant is observed for YM3 corresponding to a stronger electromagnetic absorption. The improved electromagnetic properties of the composites can be attributed to the synergistic effect between the Ba1.8Sr0.2Co2Fe11.9Pr0.1O22 and Ti3C2Tx‐MXene, which enhances the impedance matching and increases the absorption of electromagnetic waves. These improved electromagnetic properties are important in applications such as electronic devices and communication systems.

“…[110][111][112][113] The basic units of M-type ferrite and cubic spinal ferrites that retain a hexagonal crystal structure with magnetization parallel to the c-axis make up the crystal structure of Y-type. [70,114] The structure of y-type is said to be an alternate stacking of tetrahedral (T), and spinel (S) blocks parallel to the caxis with space group R-3m [115][116][117][118][119] and a = 5.9 Å and c = 43.5 Å as lattice parameters. [120,121] The formula for Y-type is A 2 M 2 Fe 12 O 22 , where A can be Ba or Sr and M is any divalent metal ion [122,123] and are attractive prospects for microwave device applications at high-frequency.…”

With the fast growth of wireless communication technology in high‐frequency ranges, electromagnetic (EM) interference has become a growing concern that has drawn international attention. The development of materials that can absorb EM radiation is a crucial solution. This review provides a detailed overview of ferrites, specifically hexagonal ferrites and their composites for microwave (MW) absorption. It examines hexagonal ferrite classifications based on the stacking order of their fundamental blocks and their synthesis methods and strategies for improving their magnetic properties. On the other hand, this review included a detailed examination of hexagonal ferrites–conducting polymer, hexagonal ferrites–2D materials, and hexagonal ferrite–other nanomaterials composites for MW absorption applications. Enhancing MW absorption in hexagonal ferrites‐based microwave absorption materials (MAMs) regulates their EM characteristics, improves impedance matching, and creates a diversity of loss mechanisms. In addition, the limitations, challenges, and opportunities of hexagonal ferrites‐based MAMs are discussed, which will be helpful to those working in related areas. As a general application potential, it is worth mentioning that, as a result of recent promising findings in the synthesis of hexagonal ferrites‐based composites, hexaferrite‐based composites are suitable devices in the area of microwave absorption.

Las hexaferritas tipo y son materiales cerámicos magnéticos, los cuales poseen una estructura cristalina compleja con grupo espacial R-3m, lo que da origen a que se presenten distintas fases magnéticas en función de la composición química y la temperatura. El aspecto más interesante desde el punto de vista tecnológico es la ferroelectricidad producida mediante spin que poseen algunas de las fases magnéticas de las hexaferritas tipo y, lo cual les confiere propiedades multiferroicas magnetoeléctricas. Con la finalidad de entender el mecanismo que da origen a las fases magnéticas en el presente trabajo se estudia el efecto de la concentración de Sr2+ en el campo de transición magnética de hexaferritas tipo y con composición química Ba1-xSrxNi2Fe11AlO22 con x = 1.0, 1.1 y 1.3.
