Achieving low resistance and high performance in magnetic tunnel junctions using high-entropy oxides

A NIMS research team has developed a magnetic tunnel junction (MTJ) featuring a tunnel barrier made of a high-entropy oxide composed of multiple metallic elements. This MTJ simultaneously demonstrated stronger perpendicular magnetization, a higher tunnel magnetoresistance (TMR) ratio (i.e., the relative change in electrical resistance when the magnetization directions of the two ferromagnetic layers switch between parallel and antiparallel alignments) and lower electrical resistance.

These properties may contribute to the development of smaller, higher-capacity and higher-performance (HDDs) and magnetoresistive random access memory (MRAM).

This research is published in Materials Today.

New Smart Pimple Patch Clears Acne in Just 7 Days

A new microarray acne patch eliminates pimples in just seven days and could pave the way for future medical treatments far beyond skincare. Waking up with a pimple does not have to be stressful. Pimple patches are small, sticker-like bandages that cover a blemish and support healing. A researc

Scientists Create Magnetic Nanohelices To Control Electron Spin at Room Temperature

Researchers in South Korea have created magnetic nanohelices that can control electron spin at room temperature. Spintronics, also called spin electronics, explores information processing by using the intrinsic angular momentum (spin) of electrons rather than only their electric charge. By tappin

Something From Nothing — Physicists Mimic the “Impossible” Schwinger Effect

Superfluid helium reveals a manageable analog to the Schwinger effect. It deepens understanding of vortices and quantum tunneling. In 1951, physicist Julian Schwinger proposed that applying a constant electric field to a vacuum could cause electron-positron pairs to emerge spontaneously, a proces

Rethinking Physics: Scientists Discover a “Giant” New Twist on a 140-Year-Old Effect

Their results pave the way for developing advanced electronic devices that rely on nonmagnetic materials. For the first time, researchers in Japan have detected a giant anomalous Hall effect (AHE) in a material that is not magnetic. The breakthrough was made using high-quality thin films of Cd3As

Worse Than We Thought: “Forever Chemicals” Are Far More Acidic Than Previously Believed

New and more precise acidity measurements may help make PFAS easier to track. Per- and polyfluoroalkyl substances (PFAS) are nicknamed “forever chemicals” in part because their acidity helps them linger in the environment. Many of these toxic chemicals are strongly acidic, so they readily shed p

Billion-Ton Waste Problem: Harvard Finds a Way To Recycle Hair Without Harsh Chemicals

A new sustainable method has been developed to break down keratins, transforming leftover wool and feathers into useful products. Every year, textile and meat-processing operations generate billions of tons of feathers, wool, and hair. These materials are rich in keratin, the tough, fibrous prote

Physicists Measured The Pulse of an Atom’s Magnetic Heart in Real Time

The pulse of an atom’s magnetic heart as it ticks back and forth between quantum states has been timed in a laboratory.

Physicists used a scanning tunneling microscope to observe electrons as they moved in sync with the nucleus of an atom of titanium-49, allowing them to estimate the duration of the core’s magnetic beat in isolation.

“These findings,” they write in their paper, “give an atomic-scale insight into the nature of nuclear spin relaxation and are relevant for the development of atomically assembled qubit platforms.”

Couples Are More Likely to Share Psychiatric Disorders, But Why?

For those partnered up in a long-term relationship, studies have shown that different health characteristics can sometimes be shared across the couple – and that extends to psychiatric disorders, according to new research.

Based on an analysis of more than 6 million couples across Taiwan, Denmark, and Sweden, an international team of researchers found that people were significantly more likely to have the same psychiatric conditions as their partners than would be expected by chance.

Those conditions included schizophrenia, attention deficit hyperactivity disorder (ADHD), depression, autism, anxiety, bipolar disorder, obsessive-compulsive disorder (OCD), substance abuse, and anorexia nervosa.
