Rotating-frame NMR relaxation in the dipolar spin glass Rb1-x(NH4)xH2AsO4

Academic Article

Abstract

  • Low-temperature T1ρ{variant} relaxation measurements of a proton pseudo-spin glass system in mixed rubidium-ammonium dihydrogen arsenate crystals are presented. The experimentally observed features of the magnetization decay in the rotating frame are explained with a model which incorporates rotational tunneling of the ammonium ions. © 1990.
