| Research Abstract |
In the past, a magnet has been understood as an assembly of classical spins (vectors). In recent decades, however, low-dimensional (low-d) quantum magnets, which cannot be explained with the classical physical picture, have attracted much attention, and various model compounds have been chemically synthesized. We aimed to achieve bottom-up fabrication of ideal low-d quantum magnets on surfaces by single atom/molecule manipulation with the scanning tunneling microscope (STM) and investigate the magnetic properties in detail and locally with spin-polarized STM. To pursue this goal, we succeeded to establish two important key techniques: single atom/molecule manipulation and spin-polarized STM.
