A new beast: antiferromagnetic quasicrystals
Scientists have made a new material that is both a quasicrystal and antiferromagnetic — a combination never seen before. Quasicrystals are a special kind of solid. Unlike normal crystals, whose atoms are arranged in repeating patterns, quasicrystals have patterns that … Continue reading

Tracking the Meissner effect under pressure
In the last two or three years, groups of scientists from around the world have made several claims that they had discovered a room-temperature superconductor. Many of these claims concerned high-pressure superconductors — materials that superconduct electricity at room temperature … Continue reading
