Magnetic and electronic phase diagram of a High Entropy Kagome System RMn₆Sn₆

The RMn₆Sn₆ family has been intensely studied in recent years due to the interplay between the Kagome derived topological electronic structures and the rare-earth dependent magnetism. Depending on the choice of rare-earth, the Mn layers can display various types of magnetic ordering over a range of temperatures. Even non-magnetic rare-earth elements  affect the magnetic coupling between the Mn Kagome layers. Here we investigate how a high-entropy alloying of six rare-earth elements affects the magnetic ordering. We present magnetization data showing three magnetic transitions and examine the longitudinal and transverse resistivities throughout different magnetic phases. We use neutron diffraction to analyze the spin structure in each phase. We discuss how rare-earth alloying impacts the anisotropy of magnetic ordering in this system.
