The study of currentvoltage characteristics (CVC) and their derivatives of tunnel contacts and hybrid heterostructures based on superconducting and ferromagnetic materials under influence microwave radiations and magnet fields in the wide range of temperatures is an actual task for development of element base of spintronics, superconducting electronics (in particular, for superconductive and quantum computers) and ultrasensitive sensors.Problem Statement. One of the modern informative physical methods for studying the properties of tunnel contacts and hybrid heterostructures based on superconducting and ferromagnetic materials is the study of CVC and their derivatives in the low temperature region (mainly liquid helium range) in a magnetic field. This includes the study of magnetoresistance, Hall effect, quantum Hall effect, in particular under the action of spin injection. Today, there is no precision complex of temperaturecontrolled cryogenic equipment for the study of CVC of tun nel contacts of superconducting materials, which could fully meet the needs of studying the parameters of super conducting materials.Purpose. Development of design and manufacture of precision temperaturecontrolled complex of cryogenic equipment for research of CVC of tunnel contacts of superconducting materials.Results. A complex of precision temperaturecontrolled cryogenic system (temperature range 2.0-300 K) has been fabricated for the study of CVC of tunnel contacts of superconducting materials. The complex is based on a liquidflow helium cryostat with builtin superconducting solenoid (SCS) (magnetic field range 0-2.9 T) and a specialized manipulator for changing the direction of the magnetic field, with a temperature regulator, with a programmable SCS power supply, automated measuring unit of CVC and software to it.
