Complex magnetic phase diagrams in Tb 2 IrAl 4 Ge 2 and Er 2 IrAl 4 Ge 2
The study investigated complex magnetic phase diagrams in single crystals of Tb2IrAl4Ge2 and Er2IrAl4Ge2, revealing rich, field-induced magnetic behavior. These materials show pronounced anisotropy and multiple successive transitions below 5 K, indicating strong crystal-electric-field effects and competing exchange interactions.
