在不久的将来，可以使用短磁场脉冲来改变磁存储器件的磁化状态。为了使这一过程所需的时间最小化，从而使这类器件的开关速度最大化，需要最大程度地抑制磁场脉冲终止后的磁化进动。实验证明，适当调整场脉冲参数可以在场脉冲终止后立即完全抑制磁化进动。
Short magnetic-field pulses may be used in the near future to change the magnetization state in magnetic storage devices. In order to minimize the time required for this process, and thus to maximize the switching speed of such devices, the magnetization precession after the termination of the magnetic-field pulse needs to be suppressed to a maximum degree. It is demonstrated experimentally that the appropriate adjustment of the field pulse parameters may lead to a full suppression of the magnetization precession immediately upon termination of the field pulse.
