Exploring Overlapping Mechanisms of Dynamic Nuclear Polarization in Type 1b HPHT Diamond
Brendan C. Sheehan, Margaret Hubble, Daphna Shimon +1
The inhomogeneous distribution of P1 centers in type 1b HPHT diamond samples allows multiple DNP mechanisms to occur within the same crystal, resulting in complex DNP spectra. At s…
Enhancing Coherence with a Clock Transition and Dynamical Decoupling in the CrMn Molecular Nanomagnet
Guanchu Chen, Brendan C. Sheehan, Ilija Nikolov +8
Molecular magnets are attractive as spin qubits due to their chemical tunability, addressability through electron-spin resonance techniques, and long coherence times. Clock transit…
Clock Transitions Generated by Defects in Silica Glass
Brendan C. Sheehan, Guanchu Chen, Jonathan R. Friedman
Clock transitions (CTs) in spin systems, which occur at avoided level crossings, enhance quantum coherence lifetimes T because the transition becomes immune to the decohering e…
The loop-zag resonator: A loop-gap resonator design for improved sensitivity in electron-spin resonance experiments
Brendan C. Sheehan, Guanchu Chen, Sai Chauhan +5
We present a novel design of loop-gap resonator, the loop-zag resonator, for sub-X-band electron-spin resonance spectroscopy. The loop-zag design can achieve improved coupling to s…
Direct Spectroscopic Observation of Berry Phase Interference in the Ni Single-Molecule Magnet
Brendan C. Sheehan, Robert Kwark, Charles A. Collett +3
Berry phase effects in spin systems lead to the suppression of tunneling effects when different tunneling paths interfere destructively. Such effects have been seen in several sing…
Adjustable coupling and in-situ variable frequency EPR probe with loop-gap resonators for spectroscopy up to X-band
G. Joshi, J. Kubasek, I. Nikolov +4
In standard electron paramagnetic resonance (EPR) spectroscopy, the frequency of an experiment is set and the spectrum is acquired using magnetic field as the independent variable.…
