Gattermann, Ulf; Röska, Benedikt; Paulmann, Carsten und Park, SoHyun (2. August 2016): Large single crystal growth of MnWO4-type materials from high-temperature solutions. In: Journal of Crystal Growth, Bd. 453: S. 40-48

Abstract

A simple high-temperature growth apparatus was constructed to obtain large crystals of chemically gradient (In, Na)-doped MnWO4 solid-solutions. This paper presents the crystal growth and characterization of both MnWO4 and epitaxially grown (In, Na):MnWO4 crystals on MnWO4. These large monolithic crystals were made in two steps: A MnWO4 crystal was grown in the crystallographic main direction [001] applying the Czochralski method, followed by the top seeded growth of (In, Na):MnWO4 solid-solutions with an oriented seed crystal of MnWO4. Such a monolithic crystal will serve to fundamental investigation of coupling properties at boundaries between various multiferroic MnWO4-type solid-solutions.
