Measurement and control - Import export

Experimental setup for express measurements of the adiabatic temperature change in the room temperature range. The setup is intended for measurements of the magnetocaloric effect (MCE), namely adiabatic temperature change (ΔТ), in the temperature range from 273 to 370 K in order to get ΔТ versus temperature dependences rapidly and evaluate suitability of using of the material under investigation as a working body of magnetic refrigerators. The measurements in the setup are conducted by the direct method with the help of a thermocouple. The magnetic field change is accomplished by linear movement of the permanent magnet magnetic field source along the measuring insert. The setup operates in automatic mode under control of the program written on LabView. The setup includes: - the desktop measuring unit, - the desktop control unit, - the ΔТ measuring system, - the control computer. The enhanced algorithm of the setup operation makes possible to investigate up to 20 samples per day.

Scanning Thermal Microscopy (SThM) is an advanced SPM mode intended for simultaneous obtaining nanoscale thermal and topography images. NTMDT’s SThM kit is able to visualize temperature and thermal conductivity distribution at the sample surface. The SThM system hardware includes electronic controller, software, and probes. SThM mode of operation with an AFM requires a specialized probe with a resistor built into the cantilever. NTMDT’s SThM module allows one to monitor the resistance changes correlated with the temperature at the end of the probe. So the system is able to monitor relative changes of sample temperature and thermal conductivity. NTMDT’s thermal probes provide better than 100 nm lateral resolution for both topography and thermal images. The specialized SThM cantilever, made of SiO2 with a thin metal layer, is deposited on the probe in such a way that the highest resistance portion of the layer is concentrated near the tip apex.
