As these devices are scaled to increasingly smaller dimensions in the pursuit of speed and storage density\, significant energy dissipation has become a center stage issue for the microelectronics industry. Instea d\, a new paradigm for logic and memory has emerged harnessing the long-ra nge order of charge\, spin\, and strain in materials (so called ferroic ma terials) that exhibit collective thresholding switching and non-volatility which enables new scaling trends in energy dissipation per operation. My group investigates and engineers the interplay between spin\, charge\, lat tice\, and orbital degrees of freedom in intrinsic and artificial systems for novel device functions. Here I will discuss the advances we have made in composite multiferroics composed of a magnetostrictive ferromagnet and a piezoelectric ferroelectric which hold promise for magnetic field sensor s and energy efficient beyond-CMOS logic by harnessing magnetoelectric tra nsduction. Enhancing device performance requires highly magnetostrictive m aterials\, however\, relatively little attention has been given to enginee ring magnetostriction in thin films. Here I will present a novel means to boost the magnetostriction\, and by extension the magnetoelectric coeffici ent\, by extending the phase stability of a chemically disordered metastab le phase of Fe1-xGax thin film alloys. Transport-based magnetoelectric cha racterization of a Fe1-xGax - [Pb(Mg1/3Nb2/3)O3]0.7-[PbTiO3]0.3 (PMN-PT) c omposite multiferroic heterostructure shows are reversible 90° electrical switch of magnetic anisotropy and a large room temperature converse magne toelectric coefficient of ~2×10-5 s m-1. I will conclude the presentation with advances toward realizing sub 250 mV write voltage and sub 100 aJ en ergy dissipation per operation performance. Bio John Heron was awarded B.S. from UC Santa Barbara in 2007 where he studied magnetic semiconducto rs in the lab of Prof. David Awschalom. For masters and Ph.D. degrees (awa rded in 2011 and 2013)\, he investigated magnetoelectric switching of thin film BiFeO3 under the mentorship of Prof. Ramamoorthy Ramesh at UC Berkel ey. Heron received the Ross N. Tucker award for superior work and scholars hip in the characterization\, development and/or use of semiconductor\, ma gnetic\, optical or electronic materials by a graduate student or students pursuing such areas of inquiry at the University of California\, Berkeley in 2013. As a postdoc in the lab of Prof. Schlom\, Heron investigated mag netoelectric switching in novel composite multiferroic heterostructures. S ince Jan. 2016\, John Heron is now Assistant Professor of Materials Scienc e and Engineering at the University of Michigan. The Heron group designs f erroic materials for energy efficient devices. He is best known for his wo rk on the pulsed laser deposition thin film ferroic and multiferroic oxide s and the characterization of magnetoelectric and multiferroic materials. Particular interest resides in interface\, spin\, structure\, and charge e ffects that occur in layered structures with ferroic materials\, such as ( anti)ferromagnets\, (anti)ferroelectrics\, and multiferroics. He was a rec ent recipient of the NSF CAREER award to investigate novel high entropy ox ide materials as prospective correlated electron systems with vast tunabil ity for new memory elements\, steep slope transistors\, and selectors.
