N2 - Ferromagnetic Mott-Hubbard insulator Lu2V2O7 has been studied under continuous Ar laser irradiation. One of the photon energies, i.e. E = 2.41 eV, corresponds to a transition from the lower Hubbard band of the V 3d orbital to the upper Hubbard band. Upon cooling, the activation-type electrical resistivity shows an anomalous drop within the temperature range of 70-130 K. Below the transition temperature, the resistivity shows no appreciable temperature dependence. The temperature increase due to the laser heating is estimated to be within the range of 15-35 K, which cannot be responsible for the observed anomalous drop of the resistivity. The metal-insulator transition is discussed in connection with the ferromagnetism of the present compound.
