All of these are known.) Then with the help of the formula: WebThe blocking temperature of these nanoparticles estimated in Section 5 was around 2 K so in the temperature range used the assembly should show superparamagnetic behaviour. The lines drawn through the data in Figure 1.11 A, are fits using the Langevin function (Equation 1.24) and the agreement is excellent in every case.
