Abstract
In this work, the SrFe12–xZnxO19 (Zn-SrM, x = 0, 0.1, 0.4, and 1.0) samples were fabricated using a combination of ball milling and heat treatment methods, which was simple and low-cost. Interestingly, the Zn-SrM samples exhibited great microwave absorption performances with an absorption rate of more than 99.99% and very thin thicknesses. The x = 0.1 sample could reach an excellent RL value of −40.08 dB at f = 17.88 GHz for a thickness of 1.45 mm. The x = 0.4 sample achieved a great RL value of −42.51 dB at 17.86 GHz and an EAB value of 1.29 GHz for t = 1.50 mm. With a thickness of 5.1 mm, the x = 1.0 sample could achieve a great RL value of −51.20 dB and an EAB value of 1.58 GHz. This microwave absorption performance, low cost, and simplicity of fabrication could confirm that Zn-SrM samples could be used as high-efficiency MAMs. The great microwave dissipating characteristics could be attributed to the high values of imaginary parts of complex permeability and complex permittivity leading to the high loss tangent, high degree of impedance matching, high values of attenuation constant and conductivity, suitable values of eddy current factor, and large numbers of semicircles in their Cole-Cole plots.
期刊介绍:
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
