ferromagnetic resonance การใช้

• Current research is suggesting that the trace elements found in the magnetite crystals of samples from deep boreholes and ferromagnetic resonance ( FMR ) spectroscopy are being used.
• Rock magnetism provides non-destructive methods for analyzing these minerals such as magnetic hysteresis measurements, temperature-dependent remanence measurements, M鰏sbauer spectroscopy, ferromagnetic resonance and so on.
• A distinguished physicist and a fellow of Magdalen College, Oxford, Griffiths was also the former head of Clarendon Laboratory of Oxford University and one of the discoverers of ferromagnetic resonance.
• His explanation of nonlinear effects in ferromagnetic resonance in known as the Suhl instability, and one of the major sources of broadening of nuclear magnetic resonance lines in magnetically ordered media is known as the Suhl-Nakamura interaction.
• The advantage of using a ferrite NIM material for phase shifter application is that it allows use of a ferrite in the negative magnetic permeability region near the FMR ( ferromagnetic resonance frequency ) when is relatively high and still maintains low losses.
• A 1935 paper published by Lev Landau and Evgeny Lifshitz predicted the existence of ferromagnetic resonance of the Larmor precession, which was independently verified in experiments by J . H . E . Griffiths ( UK ) and E . K . Zavoiskij ( USSR ) in 1946.
