Controlled growth setup. (a) Second experimental setup composed of one pair of Helmholtz coils to produce a vertical magnetic field \(B_z\) and an IR laser to create a hot spot on the liquid interface. (b) Side view of the use of the laser-induced thermocapillary flow to bring a magnetic particle closer to another one. The flow pushes the particle away from the laser spot. (c) Developed strategy to achieve a desired final state by adding a particle to an existing crystal in a particular direction.
