Tailored Magnetic Properties of a Double Tetrahedral Molecule with Mixed (1, ½) Spin

Abstract

In this paper, we study the magnetic properties of a molecule composed of two inverted spin-½ tetrahedra sharing their common vertex via a spin-1. We achieve an exact resolution using the Heisenberg model. As long as the exchange couplings are predominantly ferromagnetic, the spin structure is fully saturated and behaves like a large spin-4 unique magnet. Antiferromagnetic coupling can strongly frustrate the spins of the nanodevice. This may lead to several exotic phenomena. Therefore, the magnetization can be quantified into plateaus separated by quantum phase transitions. The work is intended to inspire researchers to develop molecular magnets as a basis for innovative nanoscale engineering applications.
