Artificial intelligence is colliding with a hard physical limit: the energy and heat of today’s silicon-based chips. As ...

While a Japanese team developed a series of Er(Ho)Co2-based magnetic cooling alloys for hydrogen cooling, a US research team used a “simple” acid treatment to increase flow of hydrogen atoms within ...

Addition of iridium leads to increased electron localization and stronger spin-orbit coupling between 3d electrons of iron and cobalt and 5d electrons of iridium, significantly enhancing the magnetic ...

Magnetic sensors quietly underpin everything from smartphone compasses to the stability systems that keep electric vehicles on the road, and the race to make them smaller, faster and more sensitive is ...

High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magnetic ...

Soft-magnetic fibers (SMFs) with small coercivity (H c), typically made from Co and Fe, are used in actuators, sensors, and electromagnetic shielding devices. These also show potential for ...

Researchers in Japan have developed a highly-sensitive magnetic Barkhausen noise (MBN) measurement system to understand the energy loss mechanisms in soft magnetic materials, which can be easily ...

If you wanted to 3D print an object that was magnetic in some areas only, you'd typically have to print two separate items out of different metals, then join them together. A new take on an existing ...

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

High entropy alloys or HEAs consist of five or more different metallic elements and are an extremely interesting class of materials with a great diversity of potential applications (see interview ...
