Lake Shore Cryotronics will share its magnetometer systems, cryogenic magnetic field-based probe stations, and magnetic sensors and instruments at the 58th Annual Magnetism and Magnetic Materials (MMM) Conference, Nov. 4 to 8 in Denver, Colo.

Lake Shore’s high-sensitivity, electromagnet-based magnetometers are used to characterize the magnetic properties of materials over a broad range of temperatures (4.2 K to 1273 K) and magnetic fields to 3.1 T. Last January, Lake Shore acquired New Jersey-based Princeton Measurements Corporation (PMC), adding the company’s MicroMag™ vibrating sample magnetometer (VSM) and alternating gradient magnetometer (AGM) systems to the Lake Shore family of products.

Lake Shore recently published two sets of application notes detailing the use of first-order-reversal-curve (FORC) measurements for characterizing the magnetic properties of materials. Information such as the irreversible magnetic interactions and coercivity distributions of these materials, while not attainable through the standard hysteresis loop method, are measurable through FORCs.

The first application note, “First-Order-Reversal-Curve (FORC) Measurements of Magnetic Materials,” discusses the FORC technique and resulting analysis, and provides example measurements from an array of Ni nanowires. The second application note, “Rock Magnetism and First-Order-Reversal-Curve (FORC) Measurements,” focuses on the FORC method’s application to Earth science, particularly the study of mineral magnetism.

Brad Dodrill, Lake Shore senior scientist and VP of Sales, and Scott Yano, Lake Shore Product Marketing Manager, will be on hand at MMM to discuss these notes.

MMM attendees can visit booth 201 to learn more about FORC measurements and Lake Shore’s line of magnetometers.
