The Coercivity, also called coercive field or coercive force, is defined in a ferromagnetic material as the value of the applied external magnetic field to reduce the magnetization of a test material (or sample) to zero after the sample has been magnetized to saturation. The magnetic parameter of Coercivity is a measure the resistance of…

ARkival’s Torque Measurements are performed with a MicroSense VSM employing an ultra-low friction, air bearing suspending the sample with virtually zero friction. The resulting torque measurement reports the actual force on the sample. All pre-measurement calibrations are directly based upon a known torque sample. ARkival’s magnetic torque measurements can accommodate solid, bulk, and thin film…

Note: Magnetic parameters of Magnetizing Force (H) and Flux density (B) used for Permeability measurements Permeability is the measure of the resistance of a material against the formation of a magnetic field. It is a measure of the magnetization that a material obtains in response to an applied magnetic field. Magnetic permeability is typically represented by the…

Demagnetization is a procedure or method used to eliminate unwanted (major or minor) magnetic fields. Demagnetization is also the reduction or elimination of magnetization. The demagnetization procedure can be performed as an automated process done in a VSM to remove residual magnetization resulting from substrate materials, magnetic artifacts, magnetic noise and exchange interactions and other…

AC Magnetics AC magnetic measurement data supplements DC magnetic data associated with slope of the VSM generated Hysteresis loop. AC magnetic data reporting addresses magnetic “Susceptibility” and supplements the DC magnetics of Permeability reporting. ARkival uses its assortment of designed and fabricated miniature coil probes for all AC magnetic measurements. The probes are used with…

Note magnetic parameter: Saturation Magnetic saturation is the state reached in a sample when increases in applied external magnetic field H cannot increase the magnetization of the material further. At saturation, the total magnetic flux density B does not increase with increases in applied external fields. Saturation is a characteristic of ferromagnetic and ferrimagnetic materials, such as iron, nickel, cobalt, and their alloys. Saturation is most…

A vibrating-sample magnetometer (VSM) is an accurate scientific instrument used to measure magnetic properties. A magnetic material sample is first magnetized via a uniform external magnetic field. The sample is then sinusoidally vibrated via linear actuator or a mechanical vibrator. The induced voltage from the magnetized sample is sensed in a close-proximity pickup coil whereby the…
