TL;DR: In this paper, the magnetic and electrical measurements carried out on the R 2 WO 6 tungstates showed a paramagnetic behaviour for samples with R=Nd, Gd, Dy and Ho and more complex one for samples having R=Sm and Eu in the temperature range 4.2-280 k and an insulating state at room temperature.

TL;DR: In this article, the authors measured the I-V characteristics of electron emission at 300 and 400 K and showed the symmetrical and linear behaviour of electron emissions, slightly higher at higher temperature.

TL;DR: In this paper, a single crystal of new cadmium and neodymium molybdate solid solution has been successfully grown by the Czochralski method and X-ray diffraction analysis confirmed that this solid solution crystallizes in the scheelite type structure, the Nd 3+ ions do not show long-range order and they are randomly distributed in the unit cell, substituting the Cd 2+ ions.

TL;DR: In this paper, the acceptor and donor vacancy centers of Cd1-3xDy2-2x⌷xMoO4 solid solution with limited homogeneity (0 3 eV at room temperature and the thermally activated conduction of the Arrhenius-type above 350 K) were analyzed.

TL;DR: Magnetic susceptibility measurements carried out on (Co,Zn)RE4W3O16 compounds revealed a disordered state of magnetic moments above 4.2 K for all compounds under study, and a weak response to magnetic field and temperature for ZnSm4W 3O16 and ZnEu4W1O16 samples, indicating a domination of van Vleck contribution as mentioned in this paper.
