Tetragonal Kondo Insulator EuCd2Sb2 Discovered via High Pressure High Temperature Synthesis
Abstract
<jats:title>Abstract</jats:title><jats:p>Magnetic and electronic properties of quantum materials heavily rely on the crystal structure even in the same chemical compositions. In this study, it is demonstrated that a layered tetragonal EuCd<jats:sub>2</jats:sub>Sb<jats:sub>2</jats:sub> structure can be obtained by treating bulk trigonal EuCd<jats:sub>2</jats:sub>Sb<jats:sub>2</jats:sub> under high pressure (6 GPa) and high temperature (600 °C). Magnetization measurements of the newly formed layered tetragonal EuCd<jats:sub>2</jats:sub>Sb<jats:sub>2</jats:sub> confirm an antiferromagnetic ordering with Neel temperature (<jats:italic>T</jats:italic><jats:sub>N</jats:sub>) around 16 K, which is significantly higher than that (<jats:italic>T</jats:italic><jats:sub>N</jats:sub> ≈ 7 K) of trigonal EuCd<jats:sub>2</jats:sub>Sb<jats:sub>2</jats:sub>, consistent with heat capacity measurements. Moreover, bad metal behavior is observed in the temperature dependence of the electrical resistivity and the resistivity shows a dramatic increase around the Neel temperature. Electronic structure calculations with local density approximation dynamic mean–field theory (LDA+DMFT) show that this material is strongly correlated with well‐formed large magnetic moments, due to Hund's coupling, which is known to dramatically suppress the Kondo scale.</jats:p>
