Abstract

The magnetic susceptibility of single crystals of TTF-TCNQ was measured along the principal directions over the temperature range from 4 K to 70 K. Definite anomalies were observed at 38 K and 54 K, the former showing hysteresis. No temperature dependent anistotropy was found. Fits to a two-gap model give a low temperature gap of 125 K and a high temperature gap of 370 K. A deviation from exponentially activated behavior was noted in the region near 48 K.
