Controlled Magnetic Thin Films Developed for Advanced Spin-Wave Electronics

Scientists from the Institute of Physics at Kazan Federal University, in collaboration with colleagues from the Moscow Institute of Physics and Technology (MIPT), have successfully grown thin films of a palladium-iron alloy with a controlled distribution of magnetic impurities using molecular beam epitaxy, as reported by the Russian Ministry of Education and Science.

The research has demonstrated that by manipulating the distribution profile of magnetic materials during synthesis, scientists can control the spectrum of standing exchange spin waves. Spin waves are a promising technology for information transmission and processing in magnonics, a rapidly growing field within spin-wave electronics.

"The development of technologies to create thin films with controlled magnetic properties opens up broad possibilities for controlling the spectrum of spin waves," the ministry stated.

This groundbreaking research was financially supported by the Russian Science Foundation and conducted at the "Heterostructures for Post-Silicon Electronics" research laboratory at the Institute of Physics, Kazan Federal University, as part of the Priority-2030 program.
