Spintronics

A team at Osaka Metropolitan University has shown that the Kondo effect, a key quantum phenomenon, behaves oppositely depending on spin size. For small spins, it suppresses magnetism, but for larger ones, it promotes magnetic order. This finding challenges long-held views and could advance quantum materials.

A team led by Rice University physicist Pengcheng Dai has confirmed emergent photon-like behavior in a quantum spin liquid material. The discovery in cerium zirconium oxide verifies a true three-dimensional quantum spin ice. This breakthrough resolves a long-standing puzzle in condensed matter physics.
