Look up YIG oscillator and filter on Google. YIG based devices use this effect on Yttrium Iron Garnets to give super wide tuning ranges at microwave frequencies. The magnetism is provided by coils and / or permanent magnets and tuning ranges of at least 8 to 1 are possible in practical devices, along with low phase noise.
