Quantum-Classical Reentrant Relaxation Crossover in Dy2Ti2O7 Spin-Ice [PDF]

, 2003
We have studied spin relaxation in the spin ice compound Dy2Ti2O7 through measurements of the a.c. magnetic susceptibility. While the characteristic spin relaxation time is thermally activated at high temperatures, it becomes almost temperature ...

Spin relaxation and decoherence of holes in quantum dots

, 2005
We investigate heavy-hole spin relaxation and decoherence in quantum dots in perpendicular magnetic fields. We show that at low temperatures the spin decoherence time is two times longer than the spin relaxation time.

Influence of Polymer Relaxation Time on the Electrospinning Process: Numerical Investigation

Polymers, 2017
“Electrospinnability”, or the ease with which a solution can be used to obtain bead-free uniform fibers, depends on a large number of parameters, including solution properties, process parameters and ambient conditions.

Electronic Spin Transport in Dual-Gated Bilayer Graphene

, 2016
The elimination of extrinsic sources of spin relaxation is key in realizing the exceptional intrinsic spin transport performance of graphene. Towards this, we study charge and spin transport in bilayer graphene-based spin valve devices fabricated in a ...
