Abstract: Preservation of materials using liquid nitrogen media has been widely used. One of them is used in the medical field, namely cryonic technology. Cryonics is a method of preservation at cold temperatures using a cryoprotectant in liquid nitrogen. To maintain the quality of the material, a sensor that can detect the temperature of liquid nitrogen is needed. Low temperature sensors with Cu and Ni based Resistance Temperature Detector with layers (RTD) have been made, but these sensors have a layer of Ni deposits that are not yet homogeneous. So quality improvement is needed by adding an external magnetic field. Based on this, the aim of this research is to synthesize a thin layer of Cu / Ni using electroplating method assisted by external magnets parallel to the ion currents
