论文摘要
基于Spintronic薄膜原理制造和表征单分散磁性纳米板的方法是一个挑战。这是由于所需的自上而下的方法，其中优化的毯子膜转移到流体中的颗粒中，而保留磁性特性是未知的磁场。在这里，我们探讨了底物共形烙印光刻（SCIL）作为一种快速且具有成本效益的制造途径。我们分析了名义1.8 UM和120 nm直径血小板的尺寸分布，并显示了制造步骤对磁性特性的影响，我们通过随着尺寸降低而通过显性磁化反转机制的变化来解释。我们表明，SCIL允许有效的大规模血小板制造，并讨论如何通过过程和材料工程来解决特定的应用要求。
Methods to fabricate and characterize monodisperse magnetic nanoplatelets for fluid/bio-based applications based on spintronic thin-film principles are a challenge. This is due to the required top-down approach where the transfer of optimized blanket films to free particles in a fluid while preserving the magnetic properties is an uncharted field. Here, we explore the use of substrate conformal imprint lithography (SCIL) as a fast and cost-effective fabrication route. We analyze the size distribution of nominal 1.8 um and 120 nm diameter platelets and show the effect of the fabrication steps on the magnetic properties which we explain through changes in the dominant magnetization reversal mechanism as the size decreases. We show that SCIL allows for efficient large-scale platelet fabrication and discuss how application-specific requirements can be solved via process and material engineering.
