This easily prevents demagnetization and failure of a sensor.

Irradiating a ferromagnet with a femtosecond laser pulse is known to induce an ultrafast demagnetization within a few hundred femtoseconds.

A demagnetization effect corresponding to the scenario in which the laser directly excites the Ni film is observed, but with a slight temporal delay.

Magnetic refrigeration, also known as adiabatic demagnetization cooling, works by exposing suitable materials to a changing magnetic field.

For reliable storage of data, the recording material needs to resist self-demagnetization, which occurs when the magnetic domains repel each other.

This is also known by low temperature physicists as adiabatic demagnetization, due to the application of the process specifically to create a temperature drop.

Here we demonstrate that direct laser irradiation is in fact not essential for ultrafast demagnetization, and that electron cascades caused by hot electron currents accomplish it very efficiently.
