Accelerating ultrafast magnetization reversal by non-local spin transfer [PDF]
Nature Communications, 2023 Under laser illumination it is possible to drive a ferromagnet to lose its magnetization. While this process can be rapid, remagnetization following this is slower, due to the universal critical slowing down near the phase transition.

Theory of Thermal Remagnetization of Permanent Magnets [PDF]
Journal of Magnetism and Magnetic Materials, 2001 A self-consistent mean-field theory explaining the thermal remagnetization (TR) of polycrystalline permanent magnets is given. The influence of the environment of a grain is treated by an inclusion approximation, relating the field inside the grain to ...
