The magnetic properties of isolated TbPc(2) molecules supported on a Cu(100) surface are investigated by X-ray magnetic circular dichroism at 8 K in magnetic fields up to 5 T. The crystal field and magnetic properties of single molecules are found to be robust upon adsorption on a metal substrate. The Tb magnetic moment has Ising-like magnetization; XMCD spectra combined with multiplet calculations show that the saturation orbital and spin magnetic moment values reach 3 and 6 mu(B), respectively.
采用 X 射线磁圆二色性技术,在 8 K 温度和高达 5 T 的磁场下,研究了孤立的 TbPc(2)分子在 Cu(100)表面上的磁性。研究发现,在金属衬底上吸附后,单个分子的晶体场和磁性仍然保持稳定。Tb 磁矩具有类 Ising 磁化特性;X 射线磁圆二色光谱与多体计算相结合表明,饱和轨道和自旋磁矩值分别达到 3 和 6 μB。
