Abstract

Single-crystal ${Cr}^{3 +}$ paramagnetic-resonance spectra have been recorded at 1.3 K and ∼19 kG for four sulfate alum crystals, in which the Al:Cr ratio varied from 215:1 to 590:1. The $g$ value of the ${Cr}^{3 +}$ ions is independent of crystal orientation, and equals 1.977±0.003. The zero-field Stark splitting $2 D$ was measured for AlK alum (Al:Cr=435:1), and equals 0.011 ${cm}^{- 1}$ . The hyperfine coupling constant $| A |$ for ${}^{53}{Cr}$ was measured as (1.6±0.05)× $10^{- 3}$ ${cm}^{- 1}$ . The paramagnetic spectra are dominated by the (-½, ½) transition, whose linewidth varied from 7 to 22 G. Spin-lattice relaxation is not strongly phonon bottlenecked, and the relaxation time varied from 2 to 3 msec at 0.95 K. With {111} planes perpendicular to the magnetic field, the (-½, ½) resonance line is favorable for dynamic pumping of proton polarization.
