New study shows unique magnetic transitions in quasicrystal-like structures
Quasicrystals are one of the most peculiar structures in nature. Owing to their characteristics that make them crystal-like yet very distinct, they have been attracting the attention of scientists ever since they were first observed. In a breakthrough study, a group of scientists in Japan showed unique magnetic transitions in structures similar to quasicrystals. This is a huge achievement in the field of materials science, as it opens doors to advancements in quasicrystal research and various potential applications. (2019-11-26)

Solid research leads physicists to propose new state of matter
The term 'superfluid quasicrystal' sounds like something a comic-book villain might use to carry out his dastardly plans. In reality, it's a new form of matter proposed by theoretical physicists at The University of Texas at Dallas in a recent study published in the journal Physical Review Letters. Their study also describes a 'recipe' for making the exotic materials in the lab. (2018-04-09)

Superconductivity in an alloy with quasicrystal structure
A Japanese research team led by Nagoya University discovered the first superconductive quasicrystal. The crystalline alloy Al-Zn-Mg became quasicrystalline when the Al content was reduced to 15 percent, while remaining a superconductor, with a very low critical temperature of ~0.05 K. The alloy behaved like a conventional weakly coupled superconductor, but the role of electronic states that are unique to quasicrystals (critical eigenstates) was not found. However, the existence of fractal superconductivity remains possible. (2018-03-26)
