Asylum Research Introduces VFM2(TM) Variable Field Module for Magnetic Atomic Force Microscopy Applications with MFP-3D(TM) AFMs



(Santa Barbara, CA), Asylum Research, the technology leader in scanning probe/atomic force microscopy, introduces the new Variable Field Module2 (VFM2) for the MFP-3D Atomic Force Microscopes (AFM).

The VFM2 is ideal for researchers who want to apply magnetic fields to their atomic force microscopy experiments and applies continuously adjustable magnetic fields parallel to the sample plane approaching one Tesla with one Gauss resolution. The module is useful for magnetic force microscopy (MFM), conductive AFM (C-AFM), and other applications where the sample's properties are magnetic field dependent.

The VFM2 easily attaches to the MFP-3D AFMs and features adjustable pole tips for optimal choice between maximum required field, sample placement and minimum field gradients. The Module uses a unique design incorporating rare earth magnets to produce the magnetic field. Maintaining a steady field produces no heat, thermal drift, or mechanical vibration. Field intensity is software controllable. An integrated Gaussmeter provides a quantitative measure of the applied magnetic field.

For experiments where combined magnetic field and a high tip-sample voltage bias are required, such as for studies of ferroelectric and piezoelectric materials, the VFM2 High Voltage Kit can be easily attached to the VFM2. The High Voltage Kit allows application of tip biases up to ±220V.

Commented Roger Proksch, President of Asylum Research, "Prior to the introduction of the VFM2, high magnetic field measurements required complicated superconducting or water-cooled magnets, neither of which were particularly friendly to low-noise, high precision AFM measurements. Our team, headed by Maarten Rutgers, has made a startling increase in field strength along with increased measurement precision and ease of use. This is truly a major step forward in ambient AFM."

Asylum Research is the technology leader in atomic force and scanning probe microscopy (AFM/SPM) for both materials and bioscience applications. Founded in 1999, we are an employee owned company dedicated to innovative instrumentation for nanoscience and nanotechnology, with over 250 years combined AFM/SPM experience among our staff. Our instruments are used for a variety of nanoscience applications in material science, physics, polymers, chemistry, biomaterials, and bioscience, including single molecule mechanical experiments on DNA, protein unfolding and polymer elasticity, as well as force measurements for biomaterials, chemical sensing, polymers, colloidal forces, adhesion, and more. Asylum's product line offers imaging and measurement capabilities for a wide range of samples, including advanced techniques such as electrical characterization (CAFM, SKPM, EFM), high voltage piezoresponse force microscopy (PFM), thermal analysis, quantitative nanoindenting, and a wide range of environmental accessories and application-ready modules.

Asylum's MFP-3D set the standard for AFM technology, with unprecedented precision and flexibility. The MFP-3D is the first AFM with true independent piezo positioning in all three axes, combined with low noise closed-loop feedback sensor technology. The MFP-3D offers both top and bottom sample viewing and easy integration with most commercially-available inverted optical microscopes.

Asylum's new Cypher AFM is the world's first new small sample AFM/SPM in over a decade, and sets the new standard as the world's fastest and highest resolution AFM. Cypher provides low-drift closed loop atomic resolution for the most accurate images and measurements possible today, >20X faster AC imaging for images in minutes instead of minutes or hours, Spot-On(TM) automated laser and photodetector alignment for easy setup, integrated thermal, acoustic and vibration control, and broad support for all major AFM/SPM scanning modes and capabilities.

Asylum Research offers the lowest cost of ownership of any AFM company. Ask us about our industry-best 2-year warranty, our legendary product and applications support, and our exclusive 6-month money-back satisfaction guarantee. We are dedicated to providing the most technically advanced AFMs for researchers who want to take their experiments to the next level. Asylum Research also distributes third party cantilevers from Olympus, Nanoworld/Nanosensors, and our own MFM and iDrive(TM) tips.
