Shrinking iron films strengthens laser-driven demagnetization

From photos and videos to documents, vast amounts of data are stored on hard drives in large data centers. These devices use tiny magnetic regions whose orientation determines the information stored. But how could data be ...

Electrical sliding switches graphene between magnetic states

In a discovery that could offer a new way to control quantum properties in two-dimensional materials, researchers at Cornell have found that electrically sliding the layers of ultrathin graphene can switch the material between ...

Tiny molecular changes, big microparticle deformation

Materials that change their shape upon exposure to light are attracting growing interest in applications such as soft robotics, microscale actuators and smart materials. However, the connection between molecular-level structural ...
