# magnetic anisotropy types present in a magnetic nanoparticle colloid

## Appears In

                        - Metrology of Magnetic Materials

Colloidal anisotropy data obtained as a function of the (technologically relevant) magnetic field showing (black squares) the development of chains parallel to the magnetic field through the uniaxial (K2) component and the agglomeration perpendicular to the magnetic field through the unidirectional (K1) component (red triangles), the development of offset nanoparticles along the length of the chain through the trigonal (K3) component (green stars), and the cubic (K4, magneto-crystalline) component (blue diamonds). (All error bars shown, but may be smaller than the symbol, and represent 2σ.)
