Investigations on temperature dependences of parameters of ¹²⁷I NQR spectrum of (BiI₃)(₁₋ₓ)(PbI₂)ₓ mixed layered semiconductor and alkaline halogens crystals
Results of investigations of the temperature dependence of NQR frequencies in the temperature range of 4.2-150 K for ¹²⁷I and ⁷⁹Br of the (BiI₃)(₁₋ₓ)(PbI₂)ₓ mixed layered semiconductor and the crystals of alkaline halogens are presented. The abnormally large absolute values of temperature coefficien...
