We present a general synthesis of transition metal difluorides (TMF₂)–carbon nanocomposite films by magnetron co-sputtering the Fe/Co and polytetrafluoroethylene (Teflon) targets. The composites consist of binary TMF₂ (TM=Fe, Co) nanoparticles with a crystallite size of ∼8nm immersed in a carbon matrix. The antiferromagnetic nature of TMF₂ nanoparticles with the Nel temperature T _N of 40 K (TM=Co) and 78 K (TM=Fe) is confirmed. The ability to create the sputter-deposited TMF₂–carbon nanocomposites may not only allow for possible energy applications but also provide a platform for investigating the particulate disordered antiferromagnets.

我们提出了通过磁控管共溅射 Fe/Co 和聚四氟乙烯 (Teflon) 靶材合成过渡金属二氟化物 (TMF _{2 )-碳纳米复合薄膜的方法。}复合材料由二元 TMF ₂ (TM=Fe, Co) 纳米颗粒组成，微晶尺寸约为 8nm，浸入碳基体中。_{TMF 2}纳米粒子的反铁磁性质得到证实，Nel 温度T _N为 40 K (TM=Co) 和 78 K (TM=Fe)。产生溅射沉积的 TMF ₂ -碳纳米复合材料的能力不仅可以用于可能的能源应用，还可以为研究颗粒无序反铁磁体提供平台。
