Abstract : The report covers the investigation of weakly interacting magnetic systems at very low temperatures. The weakly interacting magnetic systems which were covered in this investigation were helium three-a nuclear magnetic substance, cerium magnesium nitrate, - a paramagnetic salt. The lowest temperatures were achieved in the experiment on cerium magnesium nitrate with the aid of high field magnets. In addition a phase transition in chromium potassium sulphate at 200K was investigated by means of ultrasonic velocity measurements. (Author)
