Summary
The book consists of two parts. The first part (Chapters 2–4) is purely theoretical; the second part (Chapters 5–7) is mostly experimental. Chapter 2 contains the general theory of instantons and tunneling with dissipation, which is necessary for understanding the rest of the book. Chapters 3 and 4 deal with magnetic tunneling in single-domain particles and bulk materials, respectively. In Chapter 5, the consequences of tunneling for magnetic relaxation are derived and applied to experiments. Non-relaxation experiments are discussed in Chapter 6. Data on resonant spin tunneling in Mn12Ac, and their interpretation, are presented in Chapter 7. In selecting material for this book we were guided by the principle that the theory must be relevant to experiment while experiments must be relevant to magnetic tunneling. Time may prove that some are not. Lengthy theoretical formulas which are difficult to compare with experiments and experimental data the analysis of which is too complicated have been left out. No doubt, there are important results that did not enter the book because we failed to appreciate their significance. Our list of references serves the single purpose of refering the reader to the original papers that we know and understand; in no way does it constitute a complete list of important works on magnetic tunneling.
The work on this book would have been difficult or impossible without support from the National Science Foundation of the USA, the Spanish and Catalan governments, and the Banco Bilbao Vizcaya.
