Hours of instruction:

Weekly: five hours of lectures + three hours of study research work

Goals:

The course includes introducing students to the most important aspects of magnetism, magnetochemical measurements in inorganic, organic, analytical chemistry and biochemistry and types of magnetism in coordination chemistry (paramagnetism, ferromagnetism, metamagnetism and antiferromagnetism), with special emphasis on the paramagnetism of atomic and quasi atomic systems, as well as paramagnetism compounds of transition elements. Different methods of synthesis and characterization of magnetic materials will be considered as well as their application.

Syllabus:

  • Introduction to the principles and phenomenon of bulk magnetism (historical aspects; elemental concept of magnetism; various forms of bulk magnetism; measurement of bulk susceptibility; magnetochemical measurements in inorganic, organic, analytical chemistry and biochemistry).
  • Effect of electronic structure of atoms on magnetism (quantum-mechanical approach; electron spin; electronic magnetic moment; multi-electron states; spin-orbital interactions; perturbation theory and mixing of states).
  • Detailed review of aspects of bulk magnetism (spin paramagnetism; Weiss field and Curie-Weiss law; second order Zeeman effect and its consequences; bulk paramagnetism; cooperative magnetism; diamagnetism; metals in elemental state; paramagnetism as a result of nuclear spin).
  • Paramagnetism - Part I: Atomic and quasi-atomic systems (combined effect of spin and angular orbital momentum; paramagnetic susceptibility of a set of atoms; paramagnetism of lanthanide and actinide compounds).
  • Paramagnetism - Part II: compounds of transition elements (orbital cleavage in cubic ligand fields; high-spin and low-spin complexes; origin of orbital splitting; complexes with symmetry lower than cubic; orbital contribution to magnetic moment).
  • Magnetic materials (synthesis methods; characterization; application; molecular magnets; selected examples of magnetic materials).
