Physicists reveal nonlinear transport induced by quantum geometry in planar altermagnets

In recent years, many physicists and materials scientists have been studying a newly uncovered class of magnetic materials known as altermagnets. These materials exhibit a unique type of magnetism that differs from both conventional ferromagnetism and antiferromagnetism, marked by electrons whose spin varies depending on their momentum. In recent years, many physicists and materials scientists have been studying a newly uncovered class of magnetic materials known as altermagnets.
