Magnetocapacitance Turned Upside Down Offers a New Tool in Spintronics

With the ability to both increase and decrease the capacitance of magnetic tunneling junctions, spintronics will never be the same Illustration: Scientific Reports Two years ago, research out of Brown University offered up a new approach to increasing the electric storage capacity in magnetic tunneling junctions—which among other things form the backbone of read heads(…)

Integrated Photonic Circuits Shrunk Down to the Smallest Dimensions Yet

Integrated photonic circuit development compared to going from vacuum tubes to semiconductor transistors Illustration: Nanfang Yu/Columbia Engineering In a major breakthrough for optoelectronics, researchers at Columbia University have made the smallest yet integrated photonic circuit. In the process, they have managed to attain a high level of performance over a broad wavelength range, something not previously achieved. The(…)
