A new force in physics, altermagnetism, has been discovered after decades of research, even contradicting Einstein’s predictions. This unique phenomenon unites ferromagnetism and antiferromagnetism by aligning anti-parallel magnetic moments within a twisted crystal structure. The first evidence was obtained in manganese telluride thanks to advanced techniques such as photoemissive electron microscopy, paving the way for … Continue reading A New Force in Physics Discovered After Decades: Even Einstein Wouldn’t Have Predicted This
