Entangled spin states in self-assembled monolayer systems

We discuss the opportunity for creation of an entangled spin state in a self-assembled monolayer molecular system. A group of spin radicals can be transferred to the entangled state using resonant electromagnetic pulses. The magnetic dipole–dipole interaction within a group is taken into account while the same interaction between the groups is neglected. A high external magnetic field at low temperature provides the identical entangled states for all spin groups in a sample. We discuss how this entangled state can be measured in experiments using the macroscopic magnetization.
