Magnetic-Field-Tunable Superconducting Phases in K₂Cr₃As₃

Caption

A phase diagram of K₂Cr₃As₃ reveals three distinct superconducting phases for magnetic fields applied along the c-axis. Phase A and Phase B feature point-nodal gap structures associated with different paired-spin configurations, while high-field Phase C exhibits a line-nodal pz-wave gap, demonstrating how temperature and magnetic field can tune distinct superconducting and topological states.
