Reducing the duration of current pulses used to perform magnetization switching via spin–orbit torques in ferromagnetic and ferrimagnetic samples from microseconds to picoseconds leads to a continuous decrease in the energy consumption. These findings show that speed and efficiency of switching can be combined in various magnetic materials with different properties.
