Abstract: Single atoms on a surface can be useful in spintronics applications, but their spin lifetime is limited by relaxation. By cleverly employing an STM tip, one can probe the spin dynamics and disentangle different effects… read more here.

Abstract: We investigate the magnetic field and temperature dependence of the single-electron spin lifetime in silicon quantum dots and find a lifetime of 2.8 ms at a temperature of 1.1 K. We develop a model based on spin-valley… read more here.

DOI: 10.1103/physrevlett.121.127702
Abstract: We report the first observation of a large spin-lifetime anisotropy in bilayer graphene (BLG) fully encapsulated between hexagonal boron nitride. We characterize the out-of-plane (τ_{⊥}) and in-plane (τ_{∥}) spin lifetimes by oblique Hanle spin precession.… read more here.
