The great majority of experimental and theoretical studies in magnetobiology explored and tried to explain bioeffects on organisms (ranging from bacteria to humans) upon exposure to variable (AC) magnetic fields (MF) with a pure sinusoidal waveform, typically combined with a static (DC) component. In this report, a new class of signals is presented and posed as a relevant candidate for research in magnetobiology. The proposed signals are derived within the classic theory of the precession of a magnetic moment in a DC + AC MF in a parallel configuration. They display a frequency modulation such that the phase change per unit time of the applied AC field is, at all times, identical to that of the precession of the magnetic moment to which the field was tuned (considering its gyromagnetic ratio). In other words, applied AC field and precession of the 'engaged' magnetic moment are phase-locked. These phase-locked frequency modulated (PLFM) signals are discussed in the context of current literature, and possible future experimental and theoretical developments are suggested.

用于磁生物学研究的一类新信号。

磁生物学的大部分实验和理论研究都探索并试图解释当暴露于具有纯正弦波形的可变（AC）磁场（MF）且通常与静态（DC）结合时对生物体（从细菌到人类）的生物效应。）成分。在本报告中，提出了一种新的信号类别，并将其作为磁生物学研究的相关候选者。所提出的信号是在并联配置下DC + AC MF中磁矩进动的经典理论中得出的。它们显示出一种频率调制，使得施加的交流磁场每单位时间的相位变化始终与磁场被调谐到的磁矩的进动相同（考虑其旋磁比）。换一种说法，施加的交流磁场和“啮合”磁矩的进动是锁相的。这些锁相调频（PLFM）信号在当前文献中进行了讨论，并提出了可能的未来实验和理论发展。
