Magnetism’s new hotness

March 30, 2011 by Joerg Heber 5 Comments

Magnetism remains the most developed way to store digital information. The giga and terabytes of computer hard drives as well as the magnetic stripes that still are used for credit cards or hotel room keys, all function with the help of magnetic fields. There, the direction of the magnetic fields, up or down, expresses the [...]

Teaching new tricks to insulators

October 28, 2010 by Joerg Heber 5 Comments

Insulators might seem pretty boring materials for an electronic device such as a computer memory, because by the very nature of their definition, they don’t conduct any electrical current. But some insulators show some pretty intriguing properties. Amongst them are the so-called ferroelectrics. A ferroelectric is a material where positive and negative electrical charges, are [...]
