Lake Shore Cryotronics will be discussing its industry-leading systems for advanced nanoscale device and material characterization during the Nanotech Conference & Expo, June 15–18, in Washington, D.C.
Lake Shore will exhibit its industry-leading vibrating sample and alternating gradient magnetometers (VSM/AGMs) for the study of nanomagnetic composites, dots, wires, and arrays. The company’s MicroMag™ VSM/AGMs feature high sensitivity and speed, and are ideal for performing first-order-reversal-curve (FORC) measurements, which are indispensable in determining the distribution of switching and interaction fields in magnetic materials.
At the conference, Brad Dodrill, Lake Shore Senior Scientist and VP of Sales, will be presenting a poster on “First-Order-Reversal-Curve Analysis of Nanoscale Magnetic Materials,” based on a paper he co-authored with Dr. Leonard Spinu of the University of New Orleans. In it, they present FORC measurement results for an array of nickel (Ni) nanowires.
In addition to VSM/AGMs suited for FORC analysis, Lake Shore offers the 7400 Series VSM for nanoscale material study over a wide temperature range (4.2 K to 1273 K). The 7400 Series is particularly effective at detecting phase transitions and structural changes as a function of temperature and magnetic field in nanomagnetic and molecular magnetic materials.
Also at Nanotech, Lake Shore will be discussing its new THz system for non-contact materials characterization. This turnkey system enables researchers to measure spectroscopic responses across a range of THz frequencies, temperatures, and field strengths. Specifically designed for characterization of research-scale materials, the continuous wave (CW) THz spectrometer features a fiber-based optical platform for amplitude and phase detection from 0.2 THz to 1.5 THz and spectral resolution of better than 250 MHz. Photomixing via CW lasers enables users to focus acquisition time on a narrow spectral region of a sample.
The THz system supports a number of nanomaterial characterization applications, including semiconductor and circuit development, dielectric and optical research, nanoscale plasmonic device research, and nanowire thin-film applications.
Plus, Lake Shore will be discussing its comprehensive line of cryogenic, micro-manipulated probe stations. The stations enable magneto-transport, electrical and electro-optical, DC, RF, and microwave (to 67 GHz) contact probing of nanoscale electronics.
Lake Shore probe stations are unique in their ability to probe device samples at cryogenic temperatures (from 1.5 K to 475 K) and under the application of magnetic fields up to 30,000 G. These capabilities are becoming more important in the development of nanoelectronic and nanomagnetic products.
