Ohio State University physicists and their colleagues have demonstrated for the first time a type of magnetic behavior that was predicted to exist more than 50 years ago.
The behavior involves a special kind of energy transition among atoms in a very small magnet, called chromium-8 (Cr8). And while scientists have long thought that the effect was controlled purely by quantum mechanics, the magnet’s behavior appears to reflect the laws of classical physics.
The classical laws of movement and energy are ones that people experience in daily life, and they normally only apply to objects that are large enough to be seen with the naked eye. In contrast, the molecular magnet Cr8 is so small that quantum mechanics -- the science that describes the interactions of subatomic particles -- should rule its behavior.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
