A ferrite slab sample (0.8 mm × 9mm × 43 mm) is mounted in a sample coil and actuated by a pulsed rf magnetic field of 5 MHz frequency and 0.5 μs width. A dc magnetic field up to 4 kG is also applied, and the damped oscillation of the sample is detected after the rf pulse using the same coil. The resonance frequency increases as the bias field strength is increased. The amplitude of the resonance signal has a peak at an intermediate field strength of 0.7 kG. The resonance frequency and signal amplitude are maximized when the field is applied parallel to the slab surface. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR] |
