Abstract

X-band ESR measurements have been carried out on a α-(BEDT-TTF)₂KHg(SCN)₄ single crystal at temperatures between 1.5 and 30 K. The principal axis and values of g-tensor are determined. The directions of g₁ = 2.0014, g₂ = 2.0029 and g₃ = 2.0128 are near the directions of the c-, a- and 6-axis, respectively. Angular dependence of the effective g-value in the g₁;g₂-plane is much smaller than that in the g₁g₃- and g₂g₃-planes. The splitting of resonance line appears below 4.2 K. While the line width of one split line increases with decreasing temperature down to 1.5 K, that of another one is almost independent of temperature. The splitting seems to be related to the SDW state, which is suggested to exist below 8 K.
