Abstract: K1.00225 : Effects of 3d magnetic metal substitutions (Fe, Co, Ni) for V on superconducting T$_{c}$ of the ZrV$_{2}$ system
Author:
The effects of Fe, Co and Ni substitution on the crystallographic data and
superconducting transition temperature (T$_{c})$ of ZrV$_{2}$ have been
investigated through powder x-ray diffraction, static magnetization and
electrical-resistivity measurements. Variation of the room temperature
refined lattice parameters indicate that there is a movement for $a$ and unit
cell volume $v$ to decrease, linearly with increasing $x$ up to 0.4, for the
Zr(V$_{2-x}$T$_{x})$ (T = Fe, Co and Ni) alloys. Magnetic and electrical
measurements show that the superconducting transition temperature (T$_{c})$
of ZrV$_{2}$ is reduced by the doping of Fe, Co and Ni with depression rate
dT$_{c}$/dx $\sim $ -14, -17.5, and -15 K/atom {\%}, respectively. The
doping of Co has a larger effect than Fe and Ni on the decrease of T$_{c}$.
