Amazing Science Images

This false-colored electron microscopy image shows alternating lutetium (blue) and iron (green) atomic planes. An extra plane of iron #atoms (purple) was inserted every ten repeats. The rumpling of the lutetium planes (blue) drove the material into a ferroelectric state and increased the magnetism in the adjacent double iron layers (purple). Scientists have engineered a new magnetic ferroelectric at the atomic scale, opening a major path to reducing energy consumption involving ferroic materials.
