如封面插图所示，反铁磁性和铁磁性之间的平衡作用发生在A 2 MRu 5 B 2（A= Zr/Hf; M= Fe/Mn）中，这是铁磁性Fe/Mn链之间高度依赖于场的磁性相互作用的结果。DFT计算预测反铁磁性（AFM）的铁基相，但竞争的铁磁性（FM）和反铁磁性Mn基的。随后的实验发现，在所有化合物的磁跃迁的强场依赖性。更多信息可以在BPT Fokwa等人的论文全文中找到，1979页。
A balancing act between antiferromagnetism and ferromagnetism, as shown in the cover artwork, occurs in A 2 MRu 5 B 2 (A= Zr/Hf; M= Fe/Mn) as a result of highly field-dependent magnetic interactions between ferromagnetic Fe/Mn chains. DFT calculations predict antiferromagnetism (AFM) in the Fe-based phases but competing ferromagnetism (FM) and antiferromagnetism in Mn-based ones. Experiments subsequently found a strong field-dependence of the magnetic transitions in all compounds. More information can be found in the Full Paper by BPT Fokwa, et al. on page 1979.
