00:00We use electronic devices like smartphones, laptops, and gaming consoles every day.

00:06But have you ever noticed that they heat up after a while?

00:09That's because the circuits inside them aren't as efficient as they could be.

00:13When electrons move through a circuit to process and store information,

00:17they interact with atoms, losing energy and producing heat in a process called joule heating.

00:23Scientists around the world have been trying to solve this inefficiency of how we store information in electronics.

00:30This research field is called spintronics.

00:34Spintronics takes advantage of the property of electrons called spin,

00:38rather than just charge which traditional electronics relies on for processing and storing information.

00:43Researchers recently discovered a new mechanism that can generate spin currents by using a new material made of iron rhodium.

00:53Even better, the spin currents they generated were 10 times stronger than before.

00:59Typically, quantum magnetization dynamics are only detectable at extremely low temperatures.

01:06However, in our study, we leveraged a magnetic phase transition that induces strong quantum fluctuation even at room temperature.

01:16This is what enabled us to observe largest quantum spin pumping signals in an acceptable temperature range,

01:24making a significant advancement in spintronic devices.

01:28This means we're a step closer to low-power, high-performance memory and processors.

01:34Our discovery has direct implications for a device named magnetic random access memory, in short, MRAM,

01:43which is non-volatile memory technology based on magnetic materials.

01:49MRAM has already been commercialized by major semiconductor companies such as Samsung, TSMC, and global foundries.

01:59It is currently being used or considered for applications in consumer electronics, automotive systems, data centers, and also industrial IoT.

02:10Researchers say they now aim to turn these findings into real-world designs that could change the way electronics work.

02:18The hope is that this advance will help make our electronics last longer, and AI computing will require less power in the future.
