Mapping the magnetic phase diagram of Antiferromagnetic Zintl material Eu₅In₂As₆

Europium-based Zintl materials have recently garnered significant attention due to their strong interplay between magnetism and charge transport. Many of these materials exhibit intriguing effects in magnetic fields, such as colossal magnetoresistance[1,2] and angular magnetoresistance[3], which hold great potential for applications in electronics and spintronics, particularly in magnetic sensing. Owing to the presence of multiple europium sublattice sites, many Zintl phases exhibit complex magnetic ordering[4]. In this work, we map the magnetic phase diagram of Eu₅In₂As₆ using magnetization and AC susceptibility measurements. The results of the neutron scattering revealing the spin structure will also be discussed.
