We report the effect of 4f electron doping on structural, electrical and magneto-transport properties Dy doped half Heusler Y1-x(Dy)xPdBi (x =0, 0.2, 0.5, 1) thin films grown by pulsed laser deposition. The leads to lattice contraction which increases from 0% for parent x =0 sample approx 1.3% x=1 with increase in doping. transport measurements show a typical semi-metallic behaviour temperature...
