Effects of frustration on magnetic molecules: a survey from Olivier Kahn till today

Abstract

In magnetism, of which molecular magnetism is a part, the term frustration is used rather sloppily. Sometimes one gains the impression that if the reason for some phenomenon is not quite clear then it is attributed to frustration. In this paper I discuss the effects of frustration that I feel are relevant for the field of molecular magnetism. As will become clear later they indeed lead to a variety of unusual magnetic properties.
