magnetWhat do we get when we put an American, an English, and a German scientist in a lab? A magnet made out of the strongest known hydrogen bond. Dust off your science books and turn to the page where it says "hydrogen bonds" and you'll find out that they're responsible for the properties of water, as well as holding together that DNA double helix.

The new magnet contains biofluoride ions which makes the magnet stable at temperatures of up to 200 degrees Celsius. The magnetic properties of the material were measured using muons, which according to scientist Stephen Blundell, are subatomic particles that spin around when a magnetic field is detected. Using this method, the scientists came to the conclusion that there's no overall magnetism at room temperature. However, implanted muons detect magnetic activities when the temperature is lowered. The decrease in temperature causes "copper magnetic moments" to align, which produces a microscopic magnetic field visible to the muons.

The team will conduct further studies on the said magnetic material in the hope of determining the extent to which bifluoride and hydrogen bonds influence the "spin arrangement" of magnetic centers.
