General Description: SpinTJ Magnetic Field Sensors

The SpinTJ magnetic sensor family builds upon Micro Magnetics’ in-house expertise developing low-field magnetic tunnel junction sensor products. Based on our proprietary fabrication processes, we have developed patented recipes for fabricating macroscopic, micron-scale, and submicron MTJ field sensors. These sensors offer unmatched spatial resolution (active areas of less than 1 μm²), superior field sensitivity (field noise on the order of 1 nanotesla), and the ability to withstand extreme environmental conditions. SpinTJ sensors have a field sensitivity 50 times better than conventional magnetoresistive read/write heads and over 1000 times better than conventional Hall-effect sensors. In addition, their small active areas guarantee a spatial resolution far exceeding any other commercially available magnetic sensor technology.

Our SpinTJ magnetic sensors are based on ultra-thin magnetic films deposited on silicon. These sensors are available in a number of packages and electrical configurations, including a plug-and-play sensor probe and an encapsulated 8-lead DIP package. We also offer custom packages and electrical configurations. Micro Magnetics also offers a standard preamplifier for signal amplification and conditioning.

Micro Magnetics’ SpinTJ magnetic sensors are already in use in a number of cutting-edge industrial and research applications, including semiconductor fault isolation, detection of single micron-size bio-magnetic particles, and static and dynamic studies of micromagnetics and domain structure in small patterned magnetic films. See our “Applications” pages for some of ways people have been using our magnetic sensor technologies.
