Spin coherence and electron spin distribution of a Silver(II) S = ½ molecular system

Abstract

The spin–lattice relaxation time, spin coherence, and spin distribution have been studied through ac susceptometry, pulse EPR, and ultralow-frequency Raman spectroscopy on a silver­(II)-derived molecular system with spin 1/2. The combination of magnetometry and spectroscopy techniques demonstrates the occurrence of slow spin magnetic relaxation induced by a spin–phonon interaction. The magnetic behavior and the spin coherence of this AgII-derived system open the door to a new cation into the scarce family of S = 1/2 slow magnetic relaxing systems for further applications in quantum technologies.
