An old physical phenomenon known as the Hall effect has revealed some new tricks, according to a team co-led by researchers at Penn State and the Massachusetts Institute of Technology (MIT). They have reported their findings, ...
Moiré superlattices are materials consisting of two layers stacked on top of each other with either a small rotational misalignment or a lattice mismatch between them. The Kondo lattice model, on the other hand, describes ...
In recent years, many physicists and materials scientists have been studying a newly uncovered class of magnetic materials known as altermagnets. These materials exhibit a unique type of magnetism that differs from both conventional ...
In 2018, a discovery in materials science sent shock waves throughout the community. A team showed that stacking two layers of graphene—a honeycomb-like layer of carbon extracted from graphite—at a precise "magic angle" ...
Topological protection provides unprecedented robustness of physical phenomena against all kinds of perturbations; but in doing so, it exercises topological censorship by hiding all kinds of interesting and important microscopic ...
A joint research group from China recently achieved the first observation of intrinsic magnetic structures in a kagome lattice by using the highly sensitive magnetic force microscopy (MFM) system of the Steady High Magnetic ...
Antiferromagnets are materials in which the magnetic moments of neighboring atoms are aligned in an alternating pattern, resulting in no net macroscopic magnetism. These materials have interesting properties that could be ...
Overcoming magnetic disorder is key to exploiting the unique properties of quantum anomalous Hall (QAH) insulators. A Monash-led team has demonstrated that the breakdown in topological protection is caused by magnetic disorder, ...
A new study led by Rice University's Qimiao Si has unveiled a new class of quantum critical metal, shedding light on the intricate interactions of electrons within quantum materials. Published in Â鶹ÒùÔºical Review Letters on ...
Typically, electrons are free agents that can move through most metals in any direction. When they encounter an obstacle, the charged particles experience friction and scatter randomly like colliding billiard balls.
