Researchers have developed an innovative method to study ultrafast magnetism in materials. They have shown the generation and application of magnetic field steps, in which a magnetic field is turned ...

Fig.1: Schematic illustration of the experimental approach. The magnetic heterostructure is first excited by a femtosecond infrared laser pulse (2.1µm wavelength), initiating the process of ...

Researchers have unveiled new information about the anomalous dynamics at play when an electric current is applied to a new class of magnetic materials called non-collinear antiferromagnets.

(Nanowerk News) Magnetization can be switched with a single laser pulse. However, it is not known whether the underlying microscopic process is scalable to the nanometer length scale, a prerequisite ...

Magnetic fields are fundamental to controlling the magnetization of materials. Under static or slowly varying conditions, a material's magnetization aligns with the external field like a compass ...
