PRAIRIE, Minn.--February 22, 2005--NVE Corporation (NasdaqSC:
NVEC) announced today that it has been awarded a one-year
contract for approximately $400,000 by the Defense Advanced
Research Projects Agency (DARPA) to develop ultra-sensitive
spin-dependent tunneling (SDT) sensor systems.
Under the contract, NVE will develop systems to detect
very small magnetic fields. Potential applications include
detection of submarines, homeland security, and compasses
for cellphones.
SDT junctions are key spintronics building blocks used
in magnetoresistive random access memory (MRAM), ultra-sensitive
sensors, and biomagnetic sensors.
SDT sensors have high sensitivity without the cost,
size, or cooling requirements of conventional magnetometer
systems.
Relying on structures as thin as a few atomic layers,
SDT junctions produce a large change in resistance through
a normally insulating layer depending on the spin of
the electrons in a sensing layer. In SDT sensors, an
external magnetic field changes the spin of electrons
in the sensing layer, producing a change in junction
resistance. In January 2004 NVE reported it had achieved
a record for SDT junction sensitivity.
"Ultra-sensitive tunnel junctions is one of our
strategic research thrusts,"
said NVE President and Chief Executive Officer Daniel
A. Baker, Ph.D. "SDT sensors have a number of potential
military, homeland security, and commercial applications,
and this contract will allow us to continue to advance
the technology."
NVE is a leader in the practical commercialization of
spintronics, a nanotechnology that many experts believe
represents the next generation of microelectronics.
NVE licenses its MRAM intellectual property and sells
spintronic products, including sensors and couplers,
to revolutionize data sensing and transmission.
