  abstract = {We report the first study of Zn1−xMnxSe:Fe2+,Cr2+ (x = 0.3) crystals by continuous wave (CW) and pulsed electron paramagnetic resonance (EPR) spectroscopic techniques. Using the advantages of pulsed EPR, spin Hamiltonian parameters for Mn2+ ions were obtained (g∥ = g⊥ = 2.0060(3), А∥ = А⊥ = 61.84·10–4 cm–1, and D = –7.1·10–4 cm–1). The temperature dependence of the spin relaxation times of Mn2+ ions was described using the Orbach process for TM–1 and the Raman mechanisms for T1–1. The spin Hamiltonian parameters for Cr2+ ions were determined from the analysis of the angular dependence of CW EPR spectra (g⊥ = 1.98, g∥ = 1.961, D = –2.48 cm–1, and a = 0.02 cm–1). Moreover, an anisotropic ferromagnetic resonance (FMR) line was observed, the nature of which has yet to be clarified.},
