Control Of The Inhomogeneity Degree By Magnetic Dilution In Crystals Of Antiferromagnetic Molecular Rings

Abstract

Employing the electron spin in solid-state qubits is considered a promising method for quantum information processing. In this context, we present a microwave spectroscopic study on magnetically dilute crystals of Fe18 antiferromagnetic molecular rings. Doping with Ga3+, at concentrations ranging from 0.5% down to 0.005%, results in magnetic Fe17 Ga (S=5/2) molecules dispersed throughout the lattice, with 2-8 nm average intermolecular separation. The results reveal a significant decrease in the degree of inhomogeneity of the system, hinting at a controlled reduction in decoherence mechanisms inherent to an ensemble of anisotropic molecular magnets while maintaining the crystalline order. © 2008 The American Physical Society.
