Manipulating Ferromagnetism in Femtosecond Timescale
Extracting the fundamental physics behind every physical phenomenon is the foundation stone for its futuristic technological applications. However, probing the underlying physics becomes a challenge when it occurs in extreme dimensions either in space (nanometre) or time (nanosecond). From the textbook physics we know that the magnetic moments, inside a ferromagnetic material, are aligned in a particular direction when subjected to an external magnetic field.
