Abstract
Resistance and magnetoresistance measurements are presented for specimens of Li(NH3)4 with mole ratios of 4:1, NH3:Li. Measurements were made using a probeless, mutual inductance technique from 1.5 to 4.2 K and from 10 to 100 K. The low-temperature resistivity has a largely quadratic temperature dependence, ρ=ρ(0)+BT2. The coefficient B has only a small temperature variation from 1.5 to 25 K and is independent of the residual resistivity. Near 69 K there is a local minimum in the electrical resistivity. Thermal hysteresis is observed in this region as well. We suggest that these features are characteristic of the compound Li (NH3)4 and may be due to a magnetic transition near 70 K. The magnetoresistivity was determined from 0 to 100 kG at both 1.66 and 4.2 K. It is large, with a marked decrease in field dependence above 50 kG. Our results indicate that lithium tetra-ammine is probably an uncompensated metal with a high proportion of open-orbit carriers.
