Absence of a multiglass state in some transition metal doped quantum paraelectrics

Charu Garg, Jitender Kumar, Sunil Nair

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…
