The vortex state of a magnetic nanoring has special attributes of no magnetic poles nor stray fields. The circulatory magnetization can have two chiralities:, left-handed or right-handed, for storing "0" and "1", as shown in Fig. 1.

Molecules come in well-defined lengths: Penn State MRSEC researchers have invented a technique called "Molecular Rulers," in which molecular layers of precisely defined widths coat preexisting structures and form templates for patterning new structures with ever-smaller dimensions. Advanced lift-off processing and new bilayer resists, developed in 2005, have dramatically improved the uniformity and sharpness of the nanometer-scale gaps between the parent and daughter structures. These gaps can be tailored with molecular scale precision.

Piezoeletric materials are used for a variety of actuator and sensor applications. Finding a Pb-free replacement for the popular Pb(Zr,Ti)O3 has been a major challenge for the community.

Electron paramagnetic resonance (EPR) is commonly used to manipulate and measure the magnetic moments (or spins) of electrons.  IRG-D researchers at the Princeton Center for Complex Materials (PCCM) have demonstrated a 100 fold improvement in sensitivity to the electrons’ spins by combining long-coherence donor electrons in isotopically enriched silicon with superconducting Nb microresonators.1  The PCCM researchers have previously shown that these donor impurities, each binding one electron, exhibit exceptionally

Oxide ceramics are ubiquitous in modern society- ranging from capacitors in electronic gadgets to high-tech displays. In numerous future technologies, it is necessary to "pattern" ceramic oxides in various forms, e.g., dots and lines, at the nanometer scale.

Background: The JHU MRSEC conducts extensive K-12 educational outreach programs aimed at promoting interest in and awareness of the importance of modern materials research. The MRSEC's Research Experience for Teachers (RET) program provides high school teacher the opportunity to conduct research in MRSEC and to use the MRSEC's resources for the development of classroom modules or other materials.

In addition to providing access to state-of-the-art commercially available instruments, the Northwestern University MRSEC Shared Facilities also participate in the development of new experimental methods and tools. In particular, the Ultrasound Bioprobe has been developed that combines the noninvasive nature and sensitivity of ultrasound waves with a near-field atomic force microscope mechanical probe that provides high phase sensitivity and mechanical contrast of the scattered ultrasound wave.
