Query: Tailoring Magnetism in Quantum Dots   We study magnetism in magnetically doped quantum dots as a function of
confining potential, particle numbers, temperature, and strength of Coulomb
interactions. We explore possibility of tailoring magnetism by controlling the
electron-electron Coulomb interaction, without changing the number of
particles. The interplay of strong Coulomb interactions and quantum confinement
leads to enhanced inhomogeneous magnetization which persist at higher
temperatures than in the non-interacting case. The temperature of the onset of
magnetization can be controlled by changing the number of particles as well as
by modifying the quantum confinement and the strength of Coulomb interactions.
We predict a series of electronic spin transitions which arise from the
competition between the many-body gap and magnetic thermal fluctuations.
