Abstract

We report the formation of nanosize ferromagnetic MnAs crystallites imbedded in low-temperature
grown GaAs using Mn1 ion implantation and subsequent annealing. The structural and magnetic
properties of the crystallites have been characterized by transmission electron microscopy, electron
beam induced x-ray fluorescence, and superconducting quantum interference device magnetometry.
After an optimized thermal annealing at 750 °C, MnAs crystallites of 50 nm in size are formed.
These nanomagnets show room temperature ferromagnetism.
