Measurement performance of our new 10-inch VSM — read the app note

For researchers requiring higher applied magnetic fields than our 4- and 7-inch 8600 Series VSMs, we now offer a 10-inch electromagnet version (Model 8610). Providing fields as high as 3.6 T (>36 kOe), it is particularly ideal for characterizing permanent magnet materials, such as rare-earth NdFeB magnets, which typically require large fields to saturate and demagnetize the materials.

New app note on sensitive EQE characterization measurements

The landscape of photodetector and solar cell technologies has been rapidly expanded with the emergence of numerous novel material paradigms, including organic semiconductors, perovskites, and two-dimensional (2D) materials. These technology advances directly impact a broad spectrum of applications, from night vision to medical imaging and energy conversion. As materials, device architectures, and manufacturing processes evolve, external quantum efficiency (EQE) is a key metric when comparing devices and competing technologies. Source: Lakeshore…

Overcoming the challenges of cryogenic magnetic field measurements

With the growth in use, complexity, and strength of superconducting magnets, the need to characterize the fields they produce is growing as well. There are a multitude of complicating factors that make this a challenging prospect. There are many options for taking a measurement in this situation, but how do you know whether the reading you take it really measuring what you think you’re measuring? Source: Lakeshore…

How does a demagnetizer work? YouTuber uses our teslameter to find out

In the words of our favorite YouTuber, “I have always wondered how the inexpensive magnetizer-demagnetizer tool works. What’s inside it? And why are there stairs inside the demagnetizer opening?” Watch Brainiac75’s latest video, in which he sets out to answer these questions with the help of our F71 teslameter (while also offering a preview of the instrument’s forthcoming live plotting feature): Source: Lakeshore…

FastHall Station aids wide-bandgap semiconductor research at Georgia Tech

A new paper detailing the work of Georgia Tech researchers developing wide-bandgap semiconductor devices references the use of our new FastHall™ measurement technology for validating conductivity type and carrier concentrations of samples grown using a metal modulated epitaxy (MME) technique.

8600 Series VSM used for magnetic micro-robot as well as Wiegand wire research

Two recently published papers highlight the utility of our 8600 Series VSM for magnetic materials research: one in support of the development of a magnetic micro-robot for possible medical applications, and the other relating to magnetic sensing technology. Source: Lakeshore…

Why is my dilution refrigerator not getting to base temperature?

As dilution refrigerator (DR) designs enable temperatures that edge ever closer to absolute zero, the ability to accurately achieve and measure base temperatures becomes an increasing challenge. Source: Lakeshore…

The lock-in amplifier explained and reimagined

Measurement of electrical signals, voltage, and current is one of the most important methods used by researchers to characterize electronic materials. But electrical signals are often at very low levels and in the presence of noise — which can be as large as or even larger than the signal itself. Source: Lakeshore…
