Abstract: | The paramagnetic relaxation of Tb0,01 Y0,99(C2H5SO4)3·9H2O at temperatures between 1,14°K and 4,21°K has been investigated with the absorption-dispersion method at frequencies between 5 sec?1 and 10240 sec?1 and different magnetic fields. AtH=700 Oe. The relaxation time follows the equationτ ?1=[A H 3 coth (g z μ B H/2k T)+B T 7] sec?1 as a function of temperature. ForH<800 Oe the paramagnetic relaxation is influenced by cross relaxation processes between the hyperfine structure levels. |
