Materials scientists have presented a fast method for producing epsilon iron oxide and have shown that it can be useful for the development of next-generation devices. The magnetic properties of the material make it one of the most promising for use in 6G devices. The work on the new discovery appeared in the Journal of Materials Chemistry.
Epsilon Iron Oxide is an extremely rare and difficult to obtain form of the metal. Now it is produced in very small quantities, and the process takes up to a month. The authors of the study developed a method to accelerate the synthesis of epsilon iron oxide, so it is possible to reduce the production time to one day and increase the amount of the product. The technique is simple to reproduce, cheap, and easy to enter into industry. The materials needed for synthesis are iron and silicon, which are some of the most abundant elements on Earth.
The scientists noted that materials with such high ferromagnetic resonance frequencies have enormous potential for practical applications. Now terahertz technologies are booming: this is the Internet of Things, ultra-high-speed communications, highly specialized scientific devices and medical technologies of a new generation.
“While the 5G standard operates at frequencies of tens of gigahertz, our materials open the door to much higher frequencies – these are 6G and higher standards,” said Lyudmila Alyabyeva, senior researcher at the MIPT terahertz spectroscopy laboratory. “Now it’s up to the engineers, we’re happy to share information with them and look forward to holding the 6G phone in our hands.”
