Behaviour of MNPs under pulsed-DC MF

  • Thread starter TESL@
  • Start date
In summary, MNPs, or magnetic nanoparticles, are tiny particles with magnetic properties that can exhibit various behaviors when exposed to a pulsed-DC magnetic field. These behaviors are influenced by factors such as the strength and frequency of the field, the size and shape of the nanoparticles, and the surrounding environment. Commonly used techniques for studying these behaviors include magnetic relaxation measurements, magnetic resonance imaging, and vibrating sample magnetometry. The behavior of MNPs under pulsed-DC MF can differ significantly from their behavior under other types of magnetic fields, and this can have important applications in drug delivery, imaging, and cancer therapy. Ultimately, studying the behavior of MNPs under pulsed-DC MF can provide valuable insights into their fundamental properties and interactions with

Hello,

I'd like to ask how a superparamagnetic nanoparticle behaves under pulsed magnetic field (i.e. positive square wave) different than under a sinusodial AC MF. I have an idea but I need your information/opinions.

Thank you.

A pulsed field can be simply considered as a sum of sinusoidal fields at different frequencies. If you know the response at all the sinusoidal frequencies (and assuming no non-linearities) then you know the response to the square wave or any other waveform.
