Intermodulaiton Products had a display booth and gave demonstrations at the 28th International Conference on Low Temperature Physics. Our Multifrequency Lockin Amplifier (MLA) is making in-roads in to the low temperature physics community, where it has been used to multiplex the readout of mechanical oscillators working in superfluid.
Nov. 4, 2016: Review article published
The journal Current Opinions in Colloid & Interface Science published an invited review article: 'Quantitative force microscopy from a dynamic point of view' . The article describes recent developments in dynamic AFM, placing Intermodulation AFM in a broader context.
August 17, 2016: Intermodulation EFM reveals hole traps in high voltage insulation materials
Intermodulation Electrostatic Force Microscopy (ImEFM) maps the surface potential with very with high spatial resolution. By applying a DC bias to the tip (not possible with standard KPFM) the method can also study how the surface potential changes with the injection and extraction of charges in an insulator. The method was used to study individual surface-modified aluminum oxide nanoparticles embedded in a low-density polyethylene (LDPE) matrix. This material is currently of great interest for high voltage transmission cables. The experimental results were explained with a simple band structure model where localized electronic states in the band gap (hole traps) exist in the vicinity of the nanoparticles. See our publication in Nano Letters.
March 30 - April 1, 2016: 6th Multifrequency AFM conference in Madrid
The latest results with Intermodulation AFM were reported: mechanical mapping of viscoelastic surfaces, high resolution surface potential maps of graphene, machine learning to optimize material contrast, and interaction analysis in terms of force kernels. Intermodulation Products demonstrated the 42 frequency lockin at the booth.

January 26, 2016: Intermodulation Lockin recieves US Patent
The United States Patent and Trademark Office issued a patent to Intermodulation Products for the Intermodulation Lockin. The Intermodulation Analyser (ImLA)™ (also called Multifrequency Lockin Amplifier, MLA™) was preiously described in the Review of Scientific Instruments. The MLA™ enables Intermodulation Spectroscopy and Intermodulation Atomic Force Microscopy. Dr. Erik Tholén, CEO of Intermodulation Products AB and chief architect of the instrument reports: "We are really happy to see this patent come in to place, securing our technical innovation. Already in it's third generation, the MLA is starting to make a big impact in laboratories around the world. We're excited to get this fantastic instrument in to the hands of new users who want to develop there own multifrequency measurements."
October 14, 2015: Intermodulation AFM provides new insights to soft materials.
Intermodulation AFM makes ground breaking advancement in probing and understanding the viscoelastic properties of Soft material interfaces. A collaboration between the University of Mons and KTH Nanostructure Physics used Intermodulation AFM (ImAFM) and dynamic force quadratures to show that large amplitude surface motion results when dynamic AFM is performed on soft materials. Prof. David Haviland says of this work: "The observation of large amplitude surface motion changes our entire understanding of material property mapping with the AFM. No longer can we represent the interaction in terms of simple force-distance curves. ImAFM was instrumental in making these observations, and the moving surface model introduced in this work represents a new approach to probing viscoelasticity with the AFM."
