Abstract

Electron paramagnetic resonance of CrO doped K2SO crystals has been studied after x-irradiation at 77 K. The resulting species, a CrO center, has the principal g values gx=1.8743, gy=1.8507, and gz=1.9386. The EPR data indicate a small distortion of CrO tetrahedra. A temperature variation study of the spectra in the range 1.6–77 K shows that they broaden rapidly above 10 K and no motionally averaged spectrum is observed. The experimental results are discussed in terms of several effects including a possible Jahn–Teller effect.
