Carley Paulsen is Directeur de Recherche at the Institut Néel, CNRS, Grenoble. He received his Ph.D. from New York University and had postdoc positions at the Pontifícia Universidade Católica in Rio de Janeiro, Brazil, the Centre de Recherche sur les Très Basses Températures in Grenoble, Commissariat à l’Energie Atomique, in Saclay, France, and at Hokkaido University in Japan. He also spent a sabbatical year at the physics department at Cornell University. His research focuses on the magnetic properties at ultralow temperatures of various systems including molecular magnets, heavy fermions, and exotic superconductors.
A new experimental scheme allows the controlled generation and observation of magnetic avalanches, a cascade of spin flips that propagates through a magnetic sample like a three-dimensional fire.
