In-plane magnetic fields are responsible for inducing anomalous Hall effect in certain films, report researchers. By studying how these fields change electronic structures, the team discovered a large ...

New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — containing the equivalent magnetic energy of a human brain. When you ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...
