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.

The 8610 also offers the same high sensitivity (15 nemu RMS noise), measurement speed (1 T/s = 10 kOe/s), and simplified control as the other VSMs. The system software combines standard predefined measurement routines including major and minor hysteresis loops, remanence curves, second quadrant demagnetization curves, and first-order reversal curves (FORCs). The same variable temperature options available with our 4- and 7-inch electromagnet VSMs enable temperature-dependent measurements from 4.2 K to 1273 K, and the new 8610 has been specifically designed to execute high field FORC measurements quickly and with high precision. Included with the system is Real-Time FORC (RTForc™) software that enables fully automated FORC data acquisition, calculating and displaying FORC distributions in real time, significantly reducing the time required to obtain and analyze FORC data.

Model 8610 VSM App NoteFurther details about the 8610’s measurement performance can be found in this new application note. It describes how the VSM was used to characterize NdFeB and exchange-coupled barium hexaferrite permanent magnet samples, including results of high-field hysteresis, isothermal (IRM)/DC demagnetization (DCD) remanence curves, second quadrant demagnetization curves, and FORC measurements for the samples.
