Deskripsi
Understanding the interplay between superconductivity and magnetism has been a longstanding challenge in condensed matter physics. Here, the authors uncover a sensitive coupling between the two within the pressure-tuned phase diagram of EuTe 2 and find that certain magnetic orders can stabilize conventional superconductivity far exceeding the Pauli limit.
