Approach Could Produce Multifunction Nanodevices
A team led by Chang-Beom Eom, a University of Wisconsin-Madison professor of materials science and engineering, has developed a new approach for creating powerful nanodevices. The team includes UW-Madison graduate students and research associates as well as collaborators from Penn State University, the University of Michigan and the University of California, Berkeley.
Particular metal-oxide materials (including some ferrites) have a unique magneto-electric property that allows the material to switch its magnetic field when its polarization is switched by an electric field and vice versa.
Eom and his team have developed a road map to help researchers couple a material's electric and magnetic mechanisms. As they run a current through a magneto-electric device, electric signals follow the electric field like a path. The signals' ultimate destination could be a memory bank operated by a magnetic field. When the researchers switch the electric field, the signals encounter a fork in the path. Though both prongs of the fork head in a similar direction, one path is the correct one and will prompt the magnetic field to switch. This will allow the information carried by the signals to be stored in the bank. If the signals take the incorrect path, the magnetic state won't switch, the bank remains inaccessible, and the information is lost as soon as the electric field turns off.
In addition to determining the proper path for the electric signals, the team developed a matrix that ensures the cross-coupling effect is stable to allow long-term data storage. "This work will allow us to make nonvolatile magneto-electric devices at the nanoscale, meaning we can store the information even after the power is turned off," says Eom.
Editor's Note: How much field does it take and will the nano device respond to Radio Moscow?

ETS-Lindgren Optimizes MRI Services at N.Y. Hospital
ETS-Lindgren of Cedar Park, Texas successfully completed installation of its Magnetic Active Compensation System (MACS™ ) at the Beth Israel Medical Center in New York City. The MACS provides a maintenance-free, dynamic method for shielding MRI systems from low frequency environmental AC/DC magnetic interferences.
At Beth Israel Medical Center, the interference to their MRI system was due to subways located under the hospital site. This adversely affected the quality of the images produced in the MRI suite and limited the doctors' ability to accurately diagnose patients.
ETS-Lindgren's MACS product line results in a site environment that allows full use of all the functions available on an MRI system. In a big-city environment, there are many potential sources of interference that may cause an adverse effect on an MRI system, such as the subways near the Beth Israel Medical Center, or transformers, elevators and moving vehicles. The MACS protects the system from these sources of interference.
Simulator Supports Magnet for Cancer Treatment
The Opera electromagnetic simulator has played an important role in the design of the particle beam steering magnet currently being commissioned at Italy's new hadron therapy center in Milan — the Centro Nazionale di Adroterapia Oncologica (CNAO).
Weighing in at 70 tons, the 1.81 Tesla dipole magnet is believed to be the largest ever produced for medical applications, and is positioned at the end of a particle acceleration line. It turns the particle beam through 90 degrees to direct it down onto a patient treatment table.
The magnet was produced by Sigmaphi, a company specializing in custom magnetic systems and beam transport lines for particle accelerators. The CNAO specification called for a very large magnetic field region of 20 x 20cm, combined with exceptional field homogeneity.
Since post-design modifications would have had a dramatic effect on construction time and costs, Sigmaphi made extensive use of simulation using the Opera finite element analysis tool from Cobham Technical Services.
The speed of simulation was aided by Opera's ability to use Biot-Savart calculations for computing coil fields, greatly reducing the need for complex finite element meshing of the model — with its impact on computation time. The simulation helped to optimize the size and shape of field clamps on the magnet that are used to improve field homogeneity, and similar modifications to an iron collar that help enhance the fidelity of beam steering.
