- Аннотация: The intensities of magnetoelastic oscillations accompanying pulsed 180 degrees and 90 degrees magnetization switching of iran borate single crystals as well as pulsed magnetization of the crystals from a demagnetized state (with teres total magnetic moment) are compared for the first time. The amplitude A(1) of the oscillations of the signal obtained from the experimental sample by the induction method is adopted as a measure of the intensity of the magnetoelastic oscillations. ft is found that for the same pulse heights of the magnetic field H exciting the magnetization-switching or magnetizing process, the amplitudes A(1) of the oscillations observed in 90 degrees magnetization-switching and initial-magnetization processes have practically the same value, which is root 2 times smaller than the amplitude of the oscillations obtained in 180 degrees magnetization switching (reversal). It is concluded on the basis of the result obtained that the intensity of the magnetoelastic oscillations is virtually independent of the initial state of the single crystal and is determined mainly by the energy density Delta M . H acquired by the magnetic subsystem of the crystal from the external field (Delta M is the change in magnetization). Hence it follows that when iron borate is used in fast modulators for Mossbauer gamma rays it is preferable to use the 90 degrees magnetization-switching regime rather than the magnetization regime as has been done until very recently.
