Constant-adiabaticity ultralow magnetic field manipulations of parahydrogen-induced polarization: application to an AA'X spin system
Bogdan A. Rodin, James Eills, Román Picazo-Frutos +3
The field of magnetic resonance imaging with hyperpolarized contrast agents is rapidly expanding, and parahydrogen-induced polarization (PHIP) is emerging as an inexpensive and eas…
Spin-chemistry concepts for spintronics scientists
Konstantin L. Ivanov, Alexander Wagenpfahl, Carsten Deibel +1
Spin chemistry and spintronics developed independently and with different terminology. Until now, the interaction between the two fields has been very limited. In this review, we c…
Mixed-valence compounds as polarizing agents for Overhauser dynamic nuclear polarization in solids
Andrei Gurinov, Benedikt Sieland, Andrei Kuzhelev +7
In this paper we investigate a novel set of polarizing agents -- mixed-valence compounds -- by theoretical and experimental methods and demonstrate their performance in high-field…
Hyperpolarization of cis-15N,15N'-azobenzene by parahydrogen at ultralow magnetic fields
