Researchers from Tohoku University developed new ultra-small (single-digit nanometer scale) magnetic tunnel junctions (MTJs) that have sufficient retention properties and yet can be switched by a current.

Tohoku University developed 20-nm CoFeB/MgO-based MTJs in 2010, in which an "interfacial anisotropy" at the CoFeB/MgO interface was utilized. But these will not work at under 20-nm. The researchers now used a "shape anisotropy" to achieve the smaller MTJs.

Everspin announced its preliminary unaudited financial results for Q4 2017. Total revenues is estimated at $10 million to $10.2 million, up from $9 million in Q3 2017 and $7.1 million in Q4 2016. The net loss is estimated at $4.3 million to $4.5 million (down from $5.4 million in the past quarter and $6.1 million in Q4 2016).

Total cash and equivalents as of the end of 2017 was $13 million. Everspin also announced it is set to raise about $25 million in a new underwritten public offering.
