Thus far in this book, we have focused on ferroelectric and magnetic spin torque transfer memories. In this chapter, we describe the recent discoveries in the emerging field of multiferroic-based memories. In the last decade, considerable attention has been focused on the search for and characterization of new multiferroic materials as scientists and researchers have been driven by the promise of exotic materials functionality (especially electric field control of ferromagnetism). In this chapter we develop a holistic picture of multiferroic materials, including details on the nature

“…This is a perfect example of the power of epitaxial thin film growth and how it can give researchers access to high pressure and temperature phases that are not easily accessible by traditional bulk synthesis techniques. Since this time YMO has been grown on a number of other substrates including Si (0 0 1), [302,306] Pt/TiO x /SiO 2 /Si (0 0 1), [307] Ystabilized ZrO 2 (1 1 1) [308], and GaN/sapphire (0 0 0 1) [309,310] and with a wide range of deposition techniques including sputtering [306,309], spin coating [307], sol-gel processes [311], pulsed laser deposition [312,313], metal-organic chemical vapor deposition [314] and molecular beam epitaxy [309].…”

The growth and characterization of functional oxide thin films that are ferroelectric, magnetic, or both at the same time are reviewed. The evolution of synthesis techniques and how advances in in situ characterization have enabled significant acceleration in improvements to these materials are described. Methods for enhancing the properties of functional materials or creating entirely new functionality at interfaces are covered, including strain engineering and layering control at the atomic-layer level. Emerging applications of these functional oxides such as achieving electrical control of ferromagnetism and the future of these complex functional oxides is discussed.

Multiferroic materials, or materials that simultaneously possess two or more ferroic order parameters, have returned to the forefront of materials research. Driven by the desire to achieve new functionalities-such as electrical control of ferromagnetism at room temperature-researchers have undertaken a concerted effort to identify and understand the complexities of multiferroic materials. The ability to create high quality thin film multiferroics stands as one of the single most important landmarks in this flurry of research activity. In this review we discuss the basics of multiferroics including the important order parameters and magnetoelectric coupling in materials. We then discuss in detail the growth of single phase, horizontal multilayer, and vertical heterostructure multiferroics. The review ends with a look to the future and how multiferroics can be used to create new functionalities in materials.
