Five Slides About Magnetic Susceptibility

Five Slides About

Submitted by Sibrina Collins, The Charles H. Wright of Museum of African American History

This Five Slides About provides an overview of the concept of magnetic susceptibility for paramagnetic metal centers. Three methods are discussed, namely the Evans NMR Method, the magnetic balance and SQUID (Superconducting QUantum Interference Device). The availability of each method varies across institutions.

Learning Goals: 

The student will gain hands-on experience evaluating the magnetic properties of a paramagnetic metal complex.

The student will be able to calculate μeff (magnetic moment) from the χM (magnetic susceptibility) of a sample.

The student will learn and understand the connection between magnetic properties, unpaired electrons, oxidation state and ligand field strength for a given metal complex.

Implementation Notes: 

The purpose of this Five Slides About is to provide the instructor with a resource to introduce the topic of magnetic susceptibility. This could be used as a pre-lab discussion before students collect magnetic susceptibility data needed to calculate the magnetic moment for a given metal center. The slides can certainly be modified depending on the method for obtaining magnetic susceptibility data.
