Spin Coherence and Magnetization Transport in Nanometer-Scale Structures

Abstract

Highlights of the full reporting period include the construction of a custom-built low-temperature high magnetic field STM with ultra high vacuum sample preparation, the first of its kind. Key experimental results were obtained in STM studies of Kondo lattice and in behavior of Kondo effect in magnetic fields. IBM achieved its milestone of demonstrating single-atom spin-flip spectroscopy, published in Science (2004). IBM finalized its work on the spectroscopic properties of physisorbed molecular hydrogen in nanoscopic junctions, finding unusual excitations. Finally, IBM found when Mn atoms were placed near the edge of thin oxide islands, an enhanced zero bias conductance emerged, a notably clear manifestation of the Kondo effect.
