Unformatted text preview: o you can calculate the diameter of smallest nanoparticle with condition, such as
E should be larger than 100kT.
For higher capacity, you may want the materials which have high Ku.
FePt is one of the materials having high Ku = 2 x 107J/m3. Here Ku is different from
the value you use in
homework. Both of them
are fine. You can calculate the radius and diameter, r = 0.79nm, d=1.6nm
The diameter of the smallest particle (FePt) would be 1.6nm. Let’s assume ligand is oleic acid and its length is 2nm. 3...
