Physicist observes the first unpaired Weyl magnetic monopole

Similar to a magnet that always has both south and north poles, a kind of special quasiparticles in condensed matter called "Weyl Fermions" always appear in pairs with opposite chirality. There had been no experimental report ...

Emergent magnetic monopoles controlled at room temperature

Three dimensional (3D) nano-networks promise a new era in modern solid state physics with numerous applications in photonics, bio-medicine, and spintronics. The realization of 3D magnetic nano-architectures could enable ultra-fast ...

Magnetic effect without a magnet

Electric current is deflected by a magnetic field—in conducting materials, this leads to the so-called Hall effect. This effect is often used to measure magnetic fields. A surprising discovery has now been made at TU Wien, ...
