The Front Cover shows a crystallographically oriented film based on metal‐substituted ε‐iron oxide (ε‐Ga_0.45Fe_1.55O3) magnetic nanoparticles. The a‐axis of the orthorhombic crystal structure (Pna2₁ space group) is oriented out of the plane of the film. The angular dependence of the magnetic hysteresis loop shows a rectangular hysteresis loop with a coercive field of 9.7 kOe and a magnetization of 30.4 emu g^–1 at room temperature when the external field is along the out‐of‐plane direction with respect to the plane of the film, indicating that the easy axis corresponds to the crystallographic a‐axis. More information can be found in the Communication by H. Tokoro, S. Ohkoshi et al. For more on the story behind the cover research, see the Cover Profile.

前盖：由Ga取代的ε-氧化铁和磁滞回线的角度相关性组成的高度定向的磁性膜（Eur。J. Inorg。Chem。7/2018）

前盖示出了基于金属取代的ε -铁氧化物（ε -镓的晶体取向膜_0.45的Fe _1.55O3）的磁性纳米颗粒。正交晶体结构（Pna2 ₁空间群）的a轴指向薄膜平面之外。磁滞回线的角度依赖性显示一个矩形磁滞回线，当外部磁场沿相对于平面的平面外方向时，在室温下矫顽场为9.7 kOe，磁化强度为30.4 emu g ^–1膜，表明易磁化轴对应于所述晶体的一个-轴。可以在H. Tokoro，S。Ohkoshi等人的《通讯》中找到更多信息。有关封面研究背后的故事的更多信息，请参见封面资料。
