In a recent breakthrough, scientists have discovered that they can magnetize iron-vanadium alloy with laser pulses. This discovery could lead to new materials with properties that can be precisely controlled, such as magnetization, electronic structure, and optical properties. The laser pulses used to magnetize the alloy are incredibly fast, taking only a few nanoseconds to complete the process. The process works by heating the alloy with the laser pulses and introducing an external magnetic field. This causes the electrons in the alloy to become aligned with the external magnetic field, producing a magnetic material. This process can be used to create materials with a range of magnetic properties, which can be used in a variety of applications.
