Abstract:

The spin-lattice relaxation times of three lines of the electron paramagnetic resonance spectrum at 9.6 kMc sec of the Cr3 ion in cesium chrome alum have been measured as a function of temperature between 1.6 K and 4.2 K and dilution between 0 and 36 non-magnetic to magnetic ions by the steady-state saturation method. The three lines were those at the lowest field line 1, the second lowest field line 2, and the highest field line 3. The rates of relaxation increase with dilution for lines 1 and 2, and decrease with dilution for line 3. The dilution dependence for line 3 can be qualitatively explained by cross-relaxation, but the dilution dependences for lines 1 and 2 elude explanation. The relaxation rate of each resonance line shows at least two temperature dependences at each dilution. They are interpreted as arising from a combination of cross-relaxation and direct processes between 1.6 K and 3.0 K, and indirect processes between 3.0 K and 4.2 K. Author
