NMR observation of time-dependent magnetization in dilute magnetic system MnxCd1−x(HCOO)2·2(NH2)2CO

Abstract Time-dependent magnetizations are measured by proton NMR (spin-echo method) in magnetically dilute system Mn 1− x Cd x (HCOO) 2 ·2(NH 2 ) 2 CO, The time dependence of the magnetization is only observed for mixed system and is confined to the intermediate temperature region. The time-dependent magnetization will be due to the difference of the relaxation times of various magnitudes of the magnetic clusters in the magnetically dilute system.
