Our results on Exchange Spring Magnets were presented during UMC 2019. UMC2019 is devoted to the field of Ultrafast Magnetization Dynamics and in particular ultrafast dynamical processes in magnetic materials at femtosecond, picosecond, and attosecond time scales. This is the 4th UMC conference, previously held at Strasbourg, Nijmegen, and Kaiserslautern.
