Dynamic Polarization of Deuterons in d-LMN Crystal

Abstract

Dynamic polarization of deuterons in a single crystal of La₂Mg₃(NO₃)₁₂·24D₂O doped with Nd ions has been measured at 1.4 K with pumping by 35 GHz microwave. The 48 hfs components of DMR are identified with the sites of deuterons, and the enhancement factors are determined for each of them. The dependence of the polarization on the magnetic field agrees with the calculation based on the differential solid state effect. A possible effect of the quadrupole relaxation is noted.
