“…5(a) show the fit using above equation (2) to the experimental χ(T) of the Ti 0.6 V 0.4 alloy along with a Curie-Weiss term for the low temperature upturn. This low temperature feature appears to be due to paramagnetic impurities (such as other transition metal elements, Oxygen, Nitrogen and the oxides and nitrides of Vanadium as well) as in the case of Vanadium [62,63,64,65]. The values of the fitting parameters are as follows: χ(0) = 4.92 x 10 −10 WbA −1 m −1 , b = 3.88 x 10 −16 WbA −1 m −1 K −2 , T * = 512 K. The errors in the parameters estimated are less than 10 %.…”

We report experimental studies of the temperature and magnetic field dependence of resistivity and dc magnetic susceptibility and the temperature dependence of zero field heat capacity in a Ti 0.6 V 0.4 alloy. The temperature dependence of the normal state dc magnetic susceptibility in this Ti 0.6 V 0.4 alloy shows T 2 lnT behavior. The temperature dependence of resistivity follows a T 2 behaviour in the range 20-50 K. On the other hand, a term T 3 lnT is needed in the expression containing the electronic and lattice heat capacities to explain the temperature dependence of heat capacity at temperatures where T 2 dependence of resistivity is observed. Such temperature dependence of dc magnetic susceptibility, resistivity and heat capacity are indications of the presence of spin-fluctuations in the system. Further experimental evidence for the spin fluctuations is obtained in the form of a negative value of T 5 term in the temperature dependence of resistivity. The influence of spin-fluctuations on the superconducting properties of Ti 0.6 V 0.4 is discussed in detail. We show from our analysis of resistivity and the susceptibility in normal and superconducting states that the spin fluctuations present in Ti 0.6 V 0.4 alloy are itinerant in nature. There is some evidence of the existence of preformed Cooper-pairs in the temperature range well above the superconducting transition temperature. Our study indicates that the interesting correlations between spin-fluctuations and superconductivity may actually be quite widespread amongst the superconducting materials, and not necessarily be confined only to certain classes of exotic compounds.Spin-fluctuations in Ti 0.6 V 0.4

“…As a rule, the sign of Ax is the same for the elements of one row, Ax being positive for the configuration d" with even n and negative for odd 11. Appreciable deviations of the g-factor from 2 are observed in all d-metals (see, e.g., [39,401). Besides that, investigations of optical and X-ray spectra, which contain information on selection rules in L, seem to be useful for solving the problem of OMM in d-systems.…”

“…Strong anisotropy of paramagnetic susceptibility takes place in a number of hexagonal transition metals. According to review [39], in Y, Re, Ru, Os, Ax = xlI -xl < 0, the typical difference being tens per cents (however, for osmium, Ax/xll z 3). For Ti, Zr, and Hf, Ax > 0 and the anisotropy is also large.…”
