Altermagnetic Spin Splitting Effect (ASSE): Definition and Significance

Altermagnetic spin splitting effect (ASSE) is a magnetic field-induced spin splitting effect. In the presence of a magnetic field, the spin of electrons is split into spin-up and spin-down states, causing energy level splitting. This splitting effect can be observed in the band structure of materials and has a significant impact on their electronic transport and magnetic properties. ASSE is of considerable importance in materials science and condensed matter physics research, particularly in magnetic materials and spintronics, where it is widely explored and applied.
