INDIRECT MEASUREMENTS OF THE IMPURITY ELECTRON SPIN RELAXATION TIME BY NUCLEAR SPIN LATTICE RELAXATION IN CdMn ALLOYS
P. Bernier, H. Launois, H. Alloul · Le Journal de Physique Colloques · 1971
Measurements of Cd nuclear spin lattice relaxation time in CdMn alloys are presented in magnetic fields ranging from 1.4 to 30 kG, and at liquid Helium temperatures. The magnetic impurities contribution is separated into two parts from its field and temperature dependences. Our analysis attributes one to a dipolar relaxation, and the other to a scalar relaxation. An impurity electronic relaxation rate of about 2 x 109 s-1 is deduced from both.
