Hi All,
I wanted to research and design Flux gate sensor that can work in a frequency bandwidth of 1-10 MHz for high-temperature applications higher than 250 C to up to 400 C. Especially, focusing on high-frequency soft magnetic material (MnZn ferrite and Nickle zinc ferrite) as a core of magnetic sensors.
Published articles mention the frequency of operation from Dc to 3 KHz and operating temperature of less than 100 C. Amorphous ferromagnetic materials have been widely used. I could not find articles where they have used high-frequency magnetic material, Isn't it possible to use? If not, What are its limitations?
I would highly appreciate any suggestions provided! Thank you!
