Magnetic and Electronic Transport Behavior in Cr-Based Quantum Materials — •Shitao Qu, Ran Tao, Mengmeng Long, Mads Fonager Hansen, and F. Malte Grosche — Cavendish Laboratory, University of Cambridge, Cambridge, United Kingdom
Unconventional superconductivity among transition metal compounds is seen in Cu-, Fe- and most recently Ni-based materials. What about other transition metal systems? There are a surprising number of chromium-based superconductors, often in conjunction with applied pressure: CrAs, A2Cr3As3 (with A an alkaline metal), ACr3As3, and CsCr3Sb5. Moreover, CrSb is one of the best-studied metallic altermagnets. These findings motivate a wider study of Cr-based correlated electron materials.
We initially investigate (i) CrP – an isostructural and isoelectronic relative to CrAs, (ii) CrSe – an altermagnet candidate, and (iii) the Kagome lattice systems CsCr3Sb5 and CsCr6Sb6.
Single crystals are prepared via flux and vapour-transport techniques and characterised in standard X-ray, magnetometry and transport measurements. They enable studies of the electronic structure and magnetic/superconducting phase diagram, forming a promising basis for exploring correlated-electron behavior in Cr-based quantum systems more widely.
