New Magnetic Transistor Breakthrough Makes Electronics Faster While Using Less Energy
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: MIT engineers have created a magnetic transistor that enables more compact, faster, and energy-efficient electronics with built-in memory capabilities.
📈 One key stat: The new magnetic transistor can switch or amplify electric current by a factor of 10, dramatically outperforming existing magnetic transistors that change current flow by only a few percent.
💬 One key quote: “People have known about magnets for thousands of years, but there are very limited ways to incorporate magnetism into electronics. We have shown a new way to efficiently utilize magnetism that opens up a lot of possibilities for future applications and research,” says Chung-Tao Chou, an MIT graduate student.
1️⃣ The big picture: MIT researchers have developed a breakthrough magnetic transistor that could revolutionize electronic devices. By replacing silicon with chromium sulfur bromide, a magnetic semiconductor, the team has created transistors that operate more efficiently while consuming less energy. This innovation overcomes fundamental physical limitations of traditional silicon-based electronics. The new technology allows for smaller, faster circuits and uniquely incorporates built-in memory capabilities, which could simplify circuit design and enable new applications in high-performance computing.
2️⃣ Why is this good news: This technological advancement pushes electronics beyond the physical limits of silicon, potentially leading to more powerful and energy-efficient devices. The transistors require significantly less energy to operate, addressing growing concerns about electronics’ power consumption. Their built-in memory feature could simplify circuit design by combining storage and processing functions in a single component. The material remains stable in air, unlike many other experimental materials, making it more practical for real-world applications. This development opens up entirely new research avenues in spintronics, where electron spin controls electrical flow.
3️⃣ What’s next: The researchers plan to further study how to control the device using electrical current rather than external magnetic fields. They’re also working on making their fabrication method scalable to produce arrays of transistors. These improvements could move the technology closer to practical applications in commercial electronics.
