Organic Magnets Open Vast Possibilities
Researchers at the University of Victoria have discovered new
lightweight magnets that could be used in making everything from extra-thin
magnetic computer memory to ultra-light spacecraft parts.
VICTORIA, BC, CANADA -- Researchers at the University of Victoria have
discovered new lightweight magnets that could be used in making everything from
extra-thin magnetic computer memory to ultra-light spacecraft parts. A paper on
the study will appear in the Jan. 18 edition of Nature, a prestigious
international science magazine.
For decades, researchers have attempted to create an alternative to conventional
pure metal or metal alloy magnets, which are heavy, inflexible and can only be
produced under high temperatures.
The team, led by UVic chemist Dr. Robin Hicks, discovered a simple method for
making a new family of organic-based magnets by combining nickel and one of
three different organic compounds. The discovery is the first step in designing
the next generation of magnets which could, in theory, be easily manipulated at
room temperature.
The skys the limit for these magnets, in principle, says Hicks. Suppose
you want to make a particular shape of magnet these magnets could be
dissolved in solution and shaped into a different form.
Conventional magnets are a ubiquitous part of everyday life, controlling
everything from computers to cars, so I believe these new, highly processable
magnets could have endless applications.
The team will continue to fine-tune this next-generation of magnets, which
resemble black powder, to further develop their processability and commercial
potential.
