Chemistry Perspectives to Discover Novel Rare-Earth-Free Ferromagnetic Material with Strong Spin-Orbit Coupling

Invited

Abstract

Applying chemistry bonding concepts for finding novel quantum materials has been used in materials discovery. The novel family compounds APt5M (A= Mn and Fe; M= P and As) were designed and synthesized from a chemistry viewpoint. The crystal and magnetic structure characterizations show APt5M crystalizes in the anti-CeCoIn5 layered structure with 2D magnetic behaviors. Among them, MnPt5As shows ferromagnetic properties with the Tc ~287 K while MnPt5P is antiferromagnetic. According to the theoretical assessments, the 3d-5d hybridization and spin-orbit coupling on Pt are critical to their structural stability and magnetic properties. Moreover, by changing the atomic distances, we can successfully tune the magnetic properties of new materials. In this talk, I will discuss the family compounds.
