The IRM Quarterly

About the Quarterly

The IRM Quarterly is published four times each year. The Quarterly includes articles on new instruments, techniques, meeting reports and historical figures. In addition, Visiting Fellows provide a short description of the recent work at the IRM. A list of recent abstracts in the rock-magnetic literature is also maintained for each issue, and any news of interest to rock magnetists is made available. Contact the editor, Dario Bilardello (dario@umn.edu): if you would like to be placed on the email list and receive a PDF of every new issue; if you have something you would like to contribute (e.g., titles plus abstracts of papers in press, or a front-cover article); or if you have any suggestions to improve the newsletter. Links to PDFs of each issue are below.

An essential index of useful IRM Quarterly articles organized by topic is provided in The Essential IRM Quarterly Index page.

A scrollable index of the entire IRM Quarterly collection, with links to the University of Minnesota Digital Conservancy, is provided in The Fuller IRM Quarterly Index page
