Statement 1 is incorrect
Altermagnets do not exhibit net magnetization like ferromagnets. Instead, they have a unique spin structure where opposing spins cancel out, similar to antiferromagnets, leading to zero net magnetization while retaining other magnetic properties beneficial for electronic applications.
Statement 2 is correct
Altermagnets exhibit non-relativistic spin splitting, a property typically found in ferromagnets. This feature allows for efficient charge and spin transport in electronic systems, making them promising for high-speed memory devices and next-generation spintronics applications.
Statement 3 is correct
Like antiferromagnets, altermagnets possess zero net magnetization due to their opposing spin alignment. However, unlike traditional antiferromagnets, they retain spin-dependent electronic properties, offering potential advancements in magnetic memory storage and energy-efficient computing technologies.
