Magnetic properties of InMnAs nanodots prepared by MOVPE

► Zinc-blende-type InMnAs nanodots on GaAs (001) by MOVPE technology. ► Ternary composition was controled via the ratio between the partial pressure of the Mn precursor to that of the In precursor. ► Two zinc-blende structures with different lattice parameters were observed in the electron diffraction patterns. ► At a Mn content above x=0.143, zinc-blende MnAs (zb-MnAs) plays an important role in the formation of magnetic properties.
