项目摘要

Molecular spin devices (MSDs) are promising candidates for revolutionizing computer logic and memory. MSDs aim to harness the controllable transport and magnetic properties of molecular device elements which can be synthetically mass produced. However, there have been insignificant efforts to predict or measure the effect of molecular coupling on the performance of a MSD. In order to produce insights about the role of molecular device elements on the magnetic properties of the MSDs, the Research Initiation Award project entitled - A Monte Carlo and SQUID Magnetometer Study of Molecular Spintronics Devices - has two goals: a) To perform Monte Carlo Simulations (MCS) to theoretically investigate the interplay between the magnetic molecules and ferromagnetic electrodes responsible for bringing about the desired characteristics within MSDs. The project will study the effects of Heisenberg exchange coupling between magnetic molecules and ferromagnetic electrodes of a MSD; study the effect of dimensionality, geometry on the molecule induced magnetic coupling, and improvise algorithms for Monte Carlo Simulations near phase change points in a MSD. b) To experimentally study the effect of molecular device elements on the magnetic properties of the MSDs. The research will focus on magnetic tunnel junction (MTJ) based MSDs, by conducting a SQUID magnetometer based magnetization study before and after transforming a variety of MTJ test beds into MSDs by utilizing molecular device elements.
分子自旋装置(MSD)是革新计算机逻辑和存储器的很有前途的候选者。MSD的目标是利用分子器件元件的可控传输和磁性,这些元件可以合成地大规模生产。然而,在预测或测量分子耦合对MSD性能的影响方面所做的努力微不足道。为了深入了解分子器件元素对MSD磁性的作用,研究启动奖项目-分子自旋电子器件的蒙特卡罗和SQUID磁强计研究-有两个目标:a)进行蒙特卡罗模拟(MCS),从理论上研究磁性分子和铁磁电极之间的相互作用,这些电极负责在MSD中产生所需的特性。该项目将研究磁性分子与MSD铁磁电极之间的海森堡交换耦合的影响;研究维度、几何形状对分子诱导磁耦合的影响,并改进MSD相变点附近的蒙特卡罗模拟算法。B)实验研究分子器件元件对MSD磁性能的影响。本研究将集中于基于磁隧道结(MTJ)的MSD,在利用分子器件元件将各种MTJ试验台改造成MSD之前和之后进行基于SQUID磁强计的磁化研究。
