Can nanoparticles be magnetized?
Can nanoparticles be magnetized? Superparamagnetic nanoparticles are not magnetic when located in a zero magnetic field, but they quickly become magnetized when an external magnetic field is applied. When returned to a zero magnetic field they quickly revert to a non-magnetized state. Are magnetic nanoparticles expensive? Significant advantages include primarily price, stability, and compatibility—magnetic iron […]
