Continuous wave and pulsed EPR study of Cd1-xMnxTe crystals with different Mn content

Popis výsledku v původním jazyce

The cadmium manganese telluride (Cd1–xMnxTe) crystals (x<0.001 and x=0.02, 0.04, 0.1) grown using the Bridgman method were studied by applying continuous wave and pulsed electron paramagnetic resonance (EPR) spectroscopy in the wide temperature range. The Cd1–xMnxTe crystals with x < 0.001 revealed the EPR spectrum from isolated Mn2+ with g=2.0074(3),A=56.97*10–4 cm^–1,a=30.02*10–4 cm^–1, while Cd1–xMnxTe crystals with x=0.02…0.04 are characterized by two single broad isotropic EPR lines of Lorentzian shape (g~2.009 and g~1.99) due to Mn clusters of different sizes. The EPR spectrum of Cd1–xMnxTe crystals with x=0.01 consists of the single broad line at g~2.01 due to higher level of homogeneity inherent to these crystals. The temperature dependence of spin relaxation times for the isolated Mn2+ center in the Cd1–xMnxTe crystals with x<0.001 has been described using the conceptions of Orbach process for TM–1 and two-phonon Raman process for T1–1.
