Abstract
K0.05MoO2 has been studied by x-ray and Neutron diffractometry, electrical resistivity, magnetization, heat cpacity, and thermal expansion measurements. The compound displays two phase transitions, a first order phase transition near room temperature and a second order transition near 54 K. Below the transition at 54 K, a weak magnetic ordering is observed and the electrical resistivity behavior is well described by a power-law temperature dependence with exponent near 0.5. The phase transitions in the K-doped MoO2 compound have been discussed for the first time using Neutron diffraction, high resolution thermal expansion, and heat capacity measurements as a function of temperature.Citation
