The synthesis and the chemisorption from solution of a terbium bis‐phthalocyaninato complex suitable for the functionalization of lanthanum strontium manganite (LSMO) are reported. Two phosphonate groups are introduced in the double decker structure in order to allow the grafting to the ferromagnetic substrate actively used as injection electrode in organic spin valve devices. The covalent bonding of functionalized terbium bis‐phthalocyaninato system on LSMO surface preserves its molecular properties at the nanoscale. X‐ray photoelectron spectroscopy confirms the integrity of the molecules on the LSMO surface and a small magnetic hysteresis reminiscent of the typical single molecule magnet behavior of this system is detected on surface by X‐ray magnetic circular dichroism experiments. The effect of the hybrid magnetic electrode on spin polarized injection is investigated in vertical organic spin valve devices and compared to the behavior of similar spin valves embedding a single diamagnetic layer of alkyl phosphonate molecules analogously chemisorbed on LSMO. Magnetoresistance experiments have evidenced significant alterations of the magneto‐transport by the terbium bis‐phthalocyaninato complex characterized by two distinct temperature regimes, below and above 50 K, respectively.

单分子单层磁铁的垂直自旋阀的调整

据报道，适用于功能化镧锶锶锰矿（LSMO）的双酞菁ina络合物的合成和化学吸附。在双层结构中引入了两个膦酸酯基团，以允许接枝到有效用作有机自旋阀装置中的注入电极的铁磁基材。LSMO表面上功能化的双酞菁ter系统的共价键保持了纳米级的分子特性。X射线光电子能谱证实了LSMO表面上分子的完整性，并且通过X射线磁性圆二色性实验在表面上检测到了该系统典型的单分子磁体行为的微小磁滞现象。在垂直有机自旋阀装置中研究了混合磁电极对自旋极化注入的影响，并将其与类似的自旋阀的行为进行了比较，其中类似的自旋阀在LSMO上嵌入了类似化学吸附的烷基膦酸酯分子的单个抗磁性层。磁致电阻实验表明，双酞菁to复合物的磁传输发生了显着变化，其特征是分别在50 K以下和50 K以上的两个不同的温度范围。
