  The notion of artifical atom relies on the capability to change the number of
carriers one by one in semiconductor quantum dots, and the resulting changes in
their electronic structure. Organic molecules with transition metal atoms that
have a net magnetic moment and display hysteretic behaviour are known as single
molecule magnets (SMM). The fabrication of CdTe quantum dots chemically doped
with a controlled number of Mn atoms and with a number of carriers controlled
either electrically or optically paves the way towards a new concept in
nanomagnetism: the artificial single molecule magnet. Here we study the
magnetic properties of a Mn-doped CdTe quantum dot for different charge states
and show to what extent they behave like a single molecule magnet.
