Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is ...

Abstract: Magnetic sensor arrays are typically used to detect magnetic targets. Currently, research on sensor array calibration focuses on solving the problems of inconsistent sensitivity, zero offset ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...

The magnetic compass is the last unknown sense in migrating animals. For some scientists, the monarch butterfly is leading ...

Abstract: Optical sensors, commonly used in wearable devices for pulse wave monitoring, face significant limitations such as dependency on sensor positioning and variations related to skin tone. To ...
