Abstract
Static and alternating magnetic susceptibility, magnetization, and electron-spin resonance studies of Gd(III) complex [Gd2(H2O)6(C2O4)3]∙2.5H2O enabled its identification as an S = 7/2 magnet with easy-axis anisotropy D/kB = −91.2 mK and magnetic interaction effectively mediated by dipolar coupling │J/kB│ ≈ 12 mK. The magnetic field–induced slow relaxation at high temperatures is ascribed to direct relaxation with a pronounced effect of phonon bottleneck and Raman process. In contrast, relaxation at low temperatures displays reciprocating thermal behavior, where spin dynamics accelerates upon cooling. The potential origin of the observed behavior is discussed.
