Setup for measuring the resistance of thin films using the four-point method in an external magnetic field
The Nanometer 1.0 device allows for measuring the resistance and current-voltage characteristics of thin films using the four-point method in the mOhm to MOhm range. It is also possible to measure magnetoresistance by applying a small magnetic field of 50 mT.
Equipment is available based on on the terms of using research infrastructure of ACMiN. (https://acmin.agh.edu.pl/home/acmin/5_Wspolpraca/Aparatura/Zasady_i_koszty_korzystania_z_infrastruktury_badawczej_ACMiN.pdf)
The nanoMeter system can be used for general resistivity measurements, it is designed primarily for nanowires and nanolayers. It applies an electric current I to a sample in a four electrode setup, and measures the generated voltage V. The resistance R is then determined from the Ohm’s law: R = V/I. The resistance of a sample can be measured in an external magnetic field or in variable temperatures.
