Polar magnets are important materials in fundamental science and technology. However, the requirements for a polar nature are generally incompatible with those for magnetism, and thus there are few polar magnets. At the order and disorder boundaries of cations in ABO3 compounds, two polar ferromagnets of ScFeO3 with polar-corundum-type and LiNbO3-type structures were previously prepared by high-pressure synthesis. Here, we prepared a third ScFeO3 polar ferromagnet with an YMnO3-type structure using a heteroepitaxial film technique and characterized its physical properties. The YMnO3-type ScFeO3 film on a perovskite electrode showed a ferroelectric P–E hysteresis loop with Pr ∼ 4.9 μC cm−2. Only YMO-type ScFeO3 has switchable polarization by the external electric field among the three ScFeO3 polar magnets. Magnetic measurements confirmed weak ferromagnetism (TN = 195 K), which is the highest observed in the hexagonal family.

具有YMnO3型结构的可切换第三ScFeO3极性铁磁体
极性磁体是基础科学技术中的重要材料。但是，对极性的要求通常与对磁性的要求不相容，因此极性磁体很少。在ABO 3化合物中阳离子的有序和无序边界处，预先通过高压合成制备了具有极性刚玉型和LiNbO 3型结构的两个ScFeO 3极性铁磁体。在这里，我们使用异质外延薄膜技术制备了具有YMnO 3型结构的第三ScFeO 3极性铁磁体，并对其物理性质进行了表征。钙钛矿电极上的YMnO 3型ScFeO 3膜显示出铁电性P - ë磁滞回线与P - [R〜4.9μC厘米-2。在三个ScFeO 3极磁体中，只有YMO型ScFeO 3具有由外部电场引起的可切换极化。磁性测量结果证实了弱铁磁性（T N = 195 K），这是六角族中观察到的最高值。
