Site-specific spectroscopic measurement of spin and charge in (LuFeO3) m /(LuFe2O4)1 multiferroic superlattices

Autor: Shiyu Fan, Hena Das, Alejandro Rébola, Kevin A. Smith, Julia Mundy, Charles Brooks, Megan E. Holtz, David A. Muller, Craig J. Fennie, Ramamoorthy Ramesh, Darrell G. Schlom, Stephen McGill, Janice L. Musfeldt

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-9 (2020)

Understanding the inner workings of complex magnetoelectric multiferroics remains a challenge, as macroscopic techniques characterize average responses rather than the role of individual iron centers. Here, the authors reveal the origin of high-tempe

DyFe2O4: A new trigonal rare-earth ferrite grown by molecular-beam epitaxy

Autor: Rachel A. Steinhardt, Charles M. Brooks, Gabriela C. Correa, Megan E. Holtz, Ramamoorthy Ramesh, David A. Muller, Julia A. Mundy, Darrell G. Schlom

Publikováno v: APL Materials, Vol 9, Iss 4, Pp 041106-041106-7 (2021)

Using epitaxial stabilization, we synthesized single-phase (001)-oriented thin films of DyFe2O4+x on (111) MgAl2O4 substrates by molecular-beam epitaxy. The metastable DyFe2O4 polymorph formed is isostructural to known trigonal ferrimagnetic RFe2O4 p

Homologous series are layered phases that can have a range of stoichiometries depending on an index n. Examples of perovskite-related homologous series include (ABO3)nAO Ruddlesden–Popper phases and (Bi2O2) (An−1BnO3n+1) Aurivillius phases. It is

Growth of PdCoO2 by ozone-assisted molecular-beam epitaxy

Autor: Jiaxin Sun, Matthew R. Barone, Celesta S. Chang, Megan E. Holtz, Hanjong Paik, Jürgen Schubert, David A. Muller, Darrell G. Schlom

Publikováno v: APL Materials, Vol 7, Iss 12, Pp 121112-121112-7 (2019)

We report the in situ, direct epitaxial synthesis of (0001)-oriented PdCoO2 thin films on c-plane sapphire using ozone-assisted molecular-beam epitaxy. The resulting films have smoothness, structural perfection, and electrical characteristics that ri

Epitaxial crystals of Bi2Pt2O7 pyrochlore through the transformation of δ–Bi2O3 fluorite

Autor: Araceli Gutiérrez–Llorente, Howie Joress, Arthur Woll, Megan E. Holtz, Matthew J. Ward, Matthew C. Sullivan, David A. Muller, Joel D. Brock

Publikováno v: APL Materials, Vol 3, Iss 3, Pp 036105-036105-6 (2015)

Bi2Pt2O7 pyrochlore is thought to be one of the most promising oxide catalysts for application in fuel cell technology. Unfortunately, direct film growth of Bi2Pt2O7 has not yet been achieved, owing to the difficulty of oxidizing platinum metal in th
