Magnetometry Measurements: Considerations for Magnetic and First-Order-Reversal-Curve Measurements

Brad C. Dodrill, Lake Shore Cryotronics, Inc.

Magnetometers are used to characterize magnetic material properties. Magnetometry techniques can be broadly classified into two categories: inductive and force-based. Common inductive methods include vibrating sample magnetometry (VSM), extraction magnetometry, AC susceptometry and superconducting quantum interference device (SQUID) magnetometry. The two most commonly used inductive techniques are VSM and SQUID magnetometry. Alternating gradient magnetometry (AGM) is the most often used force-based technique. The measurement most commonly performed to characterize a material’s magnetic properties is that of a major hysteresis loop. <read more>

StanMagnetics Bootcamps: Basic and Advanced
August 8th
Denver, Colo.

 

MAGNETICS Magazine is pleased to announce workshops beyond those held in conjunction of our annual conference. Join us August 8th in Denver for a one-day Magentics Bootcamp, presented by Dr. Stan Trout. The Magnetics Bootcamps focus on teaching the basics of Magnetics with an emphasis on permanent magnets. If you need to understand magnets better for your job or are new to the field, the Basic Bootcamp I is the perfect place to start. Assumes that one has little or no background in magnetics. The Bootcamp I workshop will cover the essential fundamental magnetic concepts such as hysteresis, the nature of magnetism, units, basic magnet processing, magnetizing and thermal effects. If something more advanced is what you are looking for, attend Advanced Bootcamp II. Assumes someone has either taken a previous Bootcamp, (Bootcamp I), or has some technical understanding of magnetics. After a brief review of the basics, covered topics include self-demagnetization and loadlines, rare earth raw materials and their pricing, advanced processing techniques, manufacturability, design basics, case studies and what’s new on the horizon.

A Boost for Permanent Magnets
Scientists at TU Darmstadt explored on an atomic level how changes in iron content influence the micro-structure of samarium-cobalt based permanent magnets. In the long run they could contribute to the development of permanent magnets with improved magnetic performance. These magnets can be found in microwave tubes, gyroscopes and satellite controls, for instance. <read more>

 

Scientists Discover a 2-D Magnet
Magnetic materials form the basis of technologies that play increasingly pivotal roles in our lives today, including sensing and hard-disk data storage. But as our innovative dreams conjure wishes for ever-smaller and faster devices, researchers are seeking new magnetic materials that are more compact, more efficient and can be controlled using precise, reliable methods. <read more>
