摘要：
DC Hall effect measurements were made on single crystals of TTF-TCNQ in the metallic region, at atmospheric pressure, and under pressure of 6 kbars. For the field orientation employed (H parallel to the crystalline a axis) the average value of the low field Hall coefficient is minus 4. 2 plus or minus 0. 6 multiplied by 10** minus **1**1 Vcm/Ag at room temperature, which is approximately consistent with other estimates of the electron density. The influence of the electrical contacts is discussed in detail and the temperature dependence of R//H is compared with previous work on HMTSF-TCNQ.
