Discovery of Spin-Vortex-Crystal Magnetic Order in Ni- and Co- Doped CaKFe4As4
20 Jun 2019 | | Contributor(s):: Paul C. Canfield
The discovery of CaFe2As2 in 2008 revealed the extreme member of the AEFe2As2 family AE = Ba, Sr, Ca. CaFe2As2 has the smallest c-lattice parameter, manifests a strongly coupled, first-order, structural/magnetic phase transition and can be coaxed into a collapsed tetragonal phase transition,...
Aharonov-Bohm Interference of Fractional Quantum Hall Edge Modes
20 Jun 2019 | | Contributor(s):: Michael J. Manfra
The braiding statistics of certain fractional quantum Hall states can be probed via interferometry of their edge states. Practical difficulties – including loss of phase coherence – make this a challenging task. We demonstrate the operation of a small Fabry-Perot interferometer in...
