Ferromagnetic resonance oscillating field strength

Click For Summary
SUMMARY

The required oscillating field strength to induce precession of the magnetization vector in ferromagnetic materials at resonance frequencies typically ranges from 0.1 mT to 100 mT. This range is crucial for achieving a significant angle of precession. Understanding this parameter is essential for applications in magnetic resonance technologies.

Hello. What oscillating field strength, in tesla, is required to cause the magnetization vector of a ferromagnetic material to precess with a fairly large angle at its resonance frequency? I can't find this number anywhere!
