Review on crystal structures and magnetic properties of RTX ₃ materials

Abstract

The structural and compositional diversity of the RTX 3 family of materials offers various magnetic and thermodynamic properties such as complex magnetic structure, vibronic bound states, heavy-fermions, valence fluctuations, metamagnetism, spin glass behavior, quantum criticality, and unconventional superconductivity. Here we present an overview of the crystal structures, crystal growth and magnetic properties of RTX 3 compounds as well as a discussion of the relevant physics. The magnetic properties of several compounds of the RTX 3 family still remain unexplored. The compounds with a complex magnetic structure could potentially host exotic topological phases. This review article may help in the exploration of exotic magnetic properties such as the vibron state and topological spin textures.

Spin Reorientation Transition and Negative Magnetoresistance in Ferromagnetic NdCrSb3 Single Crystals

“…Benefiting from the dual magnetic structures, physics phenomena such as Dicke cooperativity effect [ 1 ], ultra-strong magnon–magnon coupling [ 2 ], and spin-phonon coupling [ 3 ] have been observed in R FeO 3 single crystals. Between the two magnetic sublattices, one of the most important interactions is the antisymmetric exchange interaction, namely the Dzyaloshinskii–Moriya (DM) interaction, which contributes to the spin reorientation (SR) transition in RMX 3 compounds [ 4 , 5 , 6 , 7 , 8 ]. The antiferromagnetic structure in YFeO 3 also yields polarized spin waves diffusing over distance and, therefore, can be used in spintronic applications [ 9 ].…”
