    • A structure and method for improving the spatial resolution of a scanning probe microscope (SPM) tip, which has been coated with a layer of chemically-synthesized nanoparticles. The nanoparticles are either single-species or heterogeneous, such that the single-species nanoparticles can be either ferromagnetic, paramagnetic, superparamagnetic, antiferromagnetic, ferrimagnetic, magneto-optic, ferroelectric, piezoelectric, superconducting, semiconducting, magnetically-doped semiconducting, insulating, fluorescent, or chemically catalytic. The layer of nanoparticles is at least two nanoparticles thick, or alternatively, is a single layer of nanoparticles thick, or alternatively, is a single layer of nanoparticles thick and covers only the tip apex portion of the tip, or alternatively, only a single nanoparticle is affixed to the tip apex. Alternatively, the layer of nanoparticles is transformed into an electrically-continuous magnetic film by annealing at a high temperature.
    • 用于改善扫描探针显微镜(SPM)尖端的空间分辨率的结构和方法,其已经涂覆有化学合成的纳米颗粒层。 纳米颗粒是单种或非均质的,使得单种纳米颗粒可以是铁磁性,顺磁性,超顺磁性,反铁磁性,亚铁磁性,磁光学,铁电体,压电,超导,半导体,磁掺杂半导体,绝缘,荧光 ,或化学催化。 纳米颗粒层是至少两个纳米颗粒厚度,或者可选地,是单层纳米颗粒的厚度,或者可选地,单层纳米颗粒是厚的,并且仅覆盖尖端的顶端部分,或者仅仅是单个纳米颗粒 贴在尖端顶端。 或者,通过在高温下退火将纳米颗粒层转变成电连续的磁性膜。
