Study finds nickelate superconductors are intrinsically magnetic

Electrons find each other repulsive. Nothing personal—it's just that their negative charges repel each other. So getting them to pair up and travel together, like they do in superconducting materials, requires a little ...

When light and electrons spin together

Theoreticians at the MPSD have demonstrated how the coupling between intense lasers, the motion of electrons, and their spin influences the emission of light on the ultrafast timescale. Their work has been published in npj ...

Quantum one-way street in topological insulator nanowires

Very thin wires made of a topological insulator could enable highly stable qubits, the building blocks of future quantum computers. Scientists see a new result in topological insulator devices as an important step towards ...

Mechanism 'splits' electron spins in magnetic material

Holding the right material at the right angle, Cornell researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet—a technique that could eventually lead to the development of more ...
