Our lab

Our laboratory is equipped with digital ADE/DMS Vibrating Sample Magnetometers, Torque Magnetometers and Analog VSMs all with computerized measurement systems to accurately characterize all types of magnetic materials.  Our computer controlled equipment provides automatic sequencing of different types of magnetic measurements that can be customized for specific applications based upon sample size, test fields, measurement planes and temperatures.

Magnetic Thermal Annealing (MTA)

ARkival’s Magnetic Thermal Annealing (MTA) process is used to enhance the performance of  magnetic materials and components. During their manufacture, preparation and processing the crystalline and magnetic  structures of these materials can assume moderate to high degrees of disorder.  The process of controlled  magnetic thermal annealing can remove these disorders and can often provide substantially improved magnetic performance of the materials and even their devices (e.g., spintronic devices).

The heating a magnetic material above its recrystallization temperature in a magnetic field and then cooling will allow atom migration within the crystal lattice such that the number of dislocation sites decreases, leading to the change in magnetic properties and at times, their ductility and hardness.

Magnetic materials such as  metals (in different shapes and forms… wires, foils and plates), powders and thin films can be thermally treated in temperatures up to 900˚C  in a uniform magnetic field (as high as 2.5 Tesla) and in an inert gas environment for MTA processing.

Curie Temperature Measurements

ARkival’s Curie temperature (TC), or Curie point measurements are designed to determine the critical temperature at which magnetic materials lose their permanent magnetic properties. Controlled temperature tests are performed in inert gas environments to determine the temperature (or temperature range) for which magnetic losses occur and the temeprature below which magnetic properties return.

Magnetic forces defined by the materials’ magnet moment result from the materials atomic structure and the determination of the Curie temperature is the point or region which a material’s intrinsic magnetic moments disorient and change direction.
