Strongly anisotropic magnetism in heavy fermion-like material

The BaAl4 parent crystal structure with the space group: I4/mmm, is at the head of a family of compounds with various novel states, like nematic superconductors, topological semimetals, heavy fermion materials, and noncentrosymmetric superconductors. Despite a plethora of well-studied compounds, many still deserve further detailed investigation. In this talk, we report on the synthesis of a Ce-Zn-Ga ternary compound in this space group and the differing properties between various batches of grown single crystals. Despite previous reports investigating the structure of the formed ternary Ce-Zn-Ga compounds, the magnetic properties have not been investigated in extensive detail. We observe highly anisotropic magnetic properties in the single crystals and compare structure analysis by refining neutron powder diffraction data. We report on the observations of low temperature magnetic ordering as well as metamagnetic transitions under field which were absent in the previous report.
