SQUID magnetometer

• Subject Area: Molecular Chemistry
• Term: Funded in 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 423442764

Magnetometry of both solid and liquid substances is among the most important research methods in the chemistry of open-shell metal complexes, bioinorganic coordination chemistry, and solid-state and material physics. Consequently, in numerous research projects of the applicants, viz. a group of chemists and physicists from Göttingen, magnetic measurements are routinely carried out, often on very air- and moisture-sensitive samples. In the field of molecular chemistry, the electronic structures of metal complexes that determine their reactivity and properties can be elucidated, and special magnetic phenomena such as single-molecule magnetism or spin-crossover can be analyzed. Planned research projects in solid state physics focus on the unique electronic and magnetic properties of thin oxide perovskite layers and heterostructures, as well as on their application potential. The existing SQUID magnetometer, which has been operated jointly by the Institute of Inorganic Chemistry (Meyer group) and the I. Physics Institute for 15 years, is now susceptible to failure. In addition, as the manufacturing of this type of device ceased in 2013, the procurement of replacement components is becoming increasingly difficult and costly. The modern SQUID magnetometer requested here is therefore considered as a replacement. It also accounts for the significant increase in sample numbers and the growing demand for high-precision measurements, since magneto-chemical aspects are now being investigated in a much larger number of research groups in the Institute of Inorganic Chemistry. Therefore, the requested device should be provided with the necessary additional equipment – e.g., with a pressure cell, a glass fiber sample holder and light source, and the AC susceptibility measurements option – to address specific questions from current and planned research projects.
