Summary on Grant Application Form
Ferroics are a class of materials that, below a certain ordering temperature, display either a long range ordering of microscopic +/- dipoles or of magnetic north-south (N/S) poles. These orderings on the microscopic atomic length scale give rise to macroscopic measurable physical properties. The +/- dipoles or N/S poles can be read and manipulated on the nanoscale by applying electronic and magnetic stimuli. In this manner existing technologies use materials like this in data storage devices where the "storage bits", the 1's and 0's correspond to the different state of either +/- or N/S. However, for next generation storage devices to improve energy consumption, increase speeds and data density, it will be desirable to have a new class of "multiferroic materials" in which these two phenomena of +/- charge dipoles and N/S magnetic state, not only coexist with one another, but are strongly coupled and depend on each other. This has significant advantages in that the data written by applying an electric field to switch a +/- state can now be read back quickly and non-destructively using a magnetic field to sense the flipping of the N/S pole. However, as yet it is still a substantial challenge to identify new materials that display this desired coupling between these two ferroic properties at or near room temperature, which would make such a device possible.

The present work uses a novel approach to enumerate the possible types of materials exhibiting these properties, leading to a systematic strategy for attempting to make and test these materials for the desired physical properties. The work will contribute both new fundamental mechanistic insight into how multiferroic materials work, and can be rationally designed, as well as providing new materials that may be tested for application in next generation storage technologies.
