The quest for imperfection

Article Abstract:

The resistance of two materials in particular, silver selenide and silver telluride are increased linearly as the applied magnetic field increases. This linear response over a large range makes these semiconductor materials attractive as magnetic-field sensors, although their performance is unusual in terms of basic physics.

A new spin on magnets

Article Abstract:

Quantum interference effects dominate the behaviour of a metallic ferromagnet at the relatively scorching temperature of liquid nitrogen. These effects may also be the explanation for a totally new mechanism behind the magnetic response of solids.

Quantum computing in molecular magnets

Article Abstract:

Research is presented concerning the implementation of Grover's algorithm through the use of solid-state systems with large spin. The use of molecular magnets to build efficient and dense memory is discussed.
