  We critically investigate the purported existence of a multiglass state in
the quantum paraelectrics SrTiO${_3}$ and KTaO${_3}$ doped with magnetic 3d
transition metals. We observe that the transition metals have limited
solubility in these hosts, and that traces of impurity magnetic oxides persist
even in the most well processed specimens. Our dielectric measurements indicate
that the polar nano-regions formed as a consequence of doping appear to lack
co-operativity, and the associated relaxation process exhibits a thermally
activated Arrhenius form. At lower temperatures, the dielectric susceptibility
could be fit using the Barrett's formalism, indicating that the
quantum-paraelectric nature of the host lattices are unaltered by the doping of
magnetic transition metal oxides. All these doped quantum paraelectrics exhibit
a crossover from the high temperature Curie-Weiss regime to one dominated by
quantum fluctuations, as evidenced by a $T{^2}$ dependence of the temperature
dependent dielectric susceptibility. The temperature dependence of the magnetic
susceptibility indicate that magnetic signatures observed in some of the
specimens could be solely ascribed to the presence of impurity oxides
corresponding to the magnetic dopants used. Hence, the doped quantum
paraelectrics appear to remain intrinsically paramagnetic down to the lowest
measured temperatures, ruling out the presence of a multiglass state.
