Enabling the rational synthesis of molecular candidates for quantum information processing requires design principles that minimize electron spin decoherence. Two series of paramagnetic coordination complexes, [M(C2O4)3]3- (M = Ru, Cr, Fe) and [M(CN)6]3- (M = Fe, Ru, Os), were prepared and subsequently interrogated by pulsed electron paramagnetic resonance spectroscopy to assess quantitatively the influence of the magnitude of spin (S = 1/2, 3/2, 5/2) and spin–orbit coupling (ζ = 464, 880, 3100 cm–1) on decoherence. The results illustrate that the design of qubit candidates can be achieved with a wide range of paramagnetic ions and spin states while preserving a long-lived coherence.
Mn-Ga has been characterized as a candidate lower-cost material for substituting rare earth materials in permanent magnets.
The high-magnetic field phase diagram to 65 Tesla of the MV2O4 family (M = Cd, Mg) reveals new multiferroic phase transitions that point to an unusual interplay between spin-orbit interactions and frustrated magnetism.
Here we study the microstructural and transport properties of Co-Ba122 thin films in which secondary non-superconducting phases have been introduced during film growth in two different ways: first by using a Co-Ba122 target with a small amount of oxygen, second by alternating two different targets: a clean CoBa122 and an undoped Ba122 target.
A prototype high-temperature superconducting coil for the 32 T all-superconducting magnet was constructed with YBCO tape and successfully tested in the large-bore resistive magnet at the MagLab.
