Abstract: M35.00010 : Atomic scale magnetic and structural imaging by achromatic electron microscopy
Here, we show that a combination of electron energy-loss magnetic chiral dichroism (EMCD)1 and chromatic-aberration-corrected transmission electron microscopy, which can provide element-selective orbital and spin magnetic moments atomic plane by atomic plane. This unique capability, which we demonstrate for Sr2FeMoO6, opens the door to local atomic level studies of spin configurations in a multitude of materials that exhibit different types of magnetic coupling, thereby contributing to a detailed understanding of physical origins of magnetic properties of materials at the highest spatial resolution2.
