Electron Chirp: Cyclotron Radiation From Single Electrons Measured Directly for First Time

A group of almost 30 scientists and engineers from six research institutions reported the direct detection of cyclotron radiation from individual electrons April 20 in Physical Review Letters. They used a specially developed spectroscopic method that allowed them to measure the energy of electrons, one single electron at a time. The method provides a new way to potentially measure the mass of the neutrino, a subatomic particle that weighs at most two-billionths of a proton.

Artificial Spin Ice: A New Playground to Better Understand Magnetism

For the first time, nanomagnet islands or arrays were arranged into an exotic structure (called "shakti") that does not directly relate to any known natural material. The "shakti" artificial spin ice configuration was fabricated and reproduced experimentally. The arrays are theoretical predictions of multiple ground states that are characteristic of frustrated magnetic materials. The results open the door to experiments on other artificial spin-ice lattices, predicted to host interesting phenomena.

New Magnetic Phase Confirms Theoretical Predictions Related to Unconventional Superconductivity

The emergence of a new magnetic phase with a square lattice before the onset of superconductivity is revealed in some iron arsenide compounds, confirming theoretical predictions of the effects of doping on magnetic interactions between the iron atoms and their relationship to high temperature superconductivity. Understanding the origin of thermodynamic phases is vital in developing a unified theory for the elusive microscopic mechanism underlying high-temperature superconductivity.

Intertwining of Superconductivity and Magnetism

Experiments on a copper-oxide superconductor reveal nearly static, spatially modulated magnetism. Because static magnetism and superconductivity do not like to coexist in the same material, the superconducting wave function is also likely modulated in space and phase-shifted to minimize overlap, consistent with recent theory. This insight will aid in writing a predictive theory for high-temperature superconductivity.

The method uses linker molecules made of complementary strands of DNA to overcome the blocks' tendency to pack together in a way that would separate differently shaped components.

Giant Magnetic Effects Induced in Hybrid Materials

For a magnetic thin film deposited onto a transition metal oxide film, the magnetic properties change dramatically as the oxide undergoes a structural phase transition.

Potential applications are envisioned in the fields of information storage and power transmission.

They found that the flux is the main driver of surface temperature change.
