What Factors Affect Magnetic Susceptibility at the Nanoscale?
Several factors influence magnetic susceptibility at the nanoscale:
Size and shape of the nanoparticles: Smaller particles may exhibit superparamagnetism, which affects their magnetic response. Surface effects: At the nanoscale, surface atoms play a significant role, altering the magnetic properties compared to bulk materials. Temperature: Magnetic susceptibility can vary with temperature, especially near the Curie temperature or Néel temperature of the material. Chemical composition: Doping or alloying can modify the magnetic properties of nanomaterials, affecting their susceptibility.
