Overview: There is a fundamental difference between chains with integer and half-integer spins; the half-integer chains are gapless and the integer ones are gapped. This statement is known as The Haldane Conjecture, it represents one of the most important problems in solid state physics nowadays and for this work Haldane received the 2016 Nobel Prize in Physics. In this proposal the PIs present the material realization of Haldanes 1D-System; a self-ordered array of 1D-metal chains where the chains length and spin can be controlled at will. The objective of this project is to apply this system to address one of the fundamental problems in magnetism: the determination of the extent and persistence of short- and long-range interactions in 1D-chains as a function of length and spin. Specifically, this research will focus in the ultra-short (and poorly explored) chains in the range of ~7 to 200 atoms long.
