Properties and Applications of Magnetic Nanoparticles

In most cases the magnetic nanoparticles range from 1 to 100 nm in size and can display superparamagnetism Superparamagnetism is caused by thermal effects that the thermal fluctuations are strong enough to spontaneously demagnetize a previously saturated assembly; therefore these particles have zero coercivity and have no hysteresis
