PREFACE

Physical Phenomena at High Magnetic Fields-IV (PPHMF-IV) was the fourth

conference sponsored by the National High Magnetic Field Laboratory (NHMFL).

The previous conferences were held in May, 1991, 1995, and 1998. These meetings

brought together experts in scientific research areas where high magnetic fields

could make an important impact.

PPHMF-III devoted substantial time to reviewing the state of many fields in

regard to the role of high magnetic fields, such as semiconductors, heavy fermions,

superconductivity, and molecular conductors. Since these topics have been

thoroughly examined in PPHMF-III, it was felt that the present conference should

be devoted to recent developments in these fields.

The conference which took place in October, 2001, at Santa Fe Convention

Center in Santa Fe, NM, was organized with invited lectures in the morning and late

afternoon and poster sessions in the early afternoon. This schedule permitted

extensive discussion with the poster contributors and was judged to be an effective

format by the 150 participants in attendance.

As in the past conferences, World Scientific was chosen to be the publisher of

the proceedings because of their excellent handling of the prior proceedings.

The editors of these proceedings are pleased to acknowledge their gratitude to

the many who worked so hard to bring about this most successful conference. We

wish to thank the staff of the NHMFL, especially Wally Thorner of the NHMFL

Educational Media Department, LeeRoy Herrera, Marion Hutton, Lou Miller and

Alice Hobbs for taking care of the correspondence and travel arrangements. We

would also like to warmly thank Julie Gallegos and Mary Layne, for their

outstanding help in organizing this conference, and handling the production issues

of these proceedings

Finally, our heartfelt thanks to those who put behind them the fears and

concerns of the September 11, 2001 events and boarded plans, trains, cars and made

the PPHMF-IV conference a tremendous success.
