The complaints offered the following comprise the notes of lectures added through the 11th iciness university of Theoretical Physics, held at Karpacz, Poland, February 19 - March four, 1974. the college used to be essentially dedicated to new recommendations within the concept of magnetism in metals, alloys, and steel compounds, yet, as could be noticeable from the desk of contents of the e-book, different issues of the speculation of magnetism have been additionally mentioned during the lec tures. The organizers agreed to any such broadening of the scope in an effort to fulfill specific requests from the Polish individuals for whose gain the varsity was once prepared. those "local" pursuits are in actual fact mirrored within the complaints and are answerable for a undeniable inhomogeneity of the subjects chosen for presentation. however, we've a robust desire that those fabrics can be attention-grabbing to many physicists, not just in Poland, for the topics mentioned listed here are very important not just at the neighborhood point, because the lectures include fairly clean, unpublished effects or very good up to-date studies. the 1st a part of the quantity includes lectures without delay cor responding to the name of the college, i.e., chosen issues of the idea of steel magnetism, with mild bias towards infrequent earth and actinide metals and their compounds. within the moment part now we have accumulated the subjects extra loosely attached with the most movement, reminiscent of statistical and thermodynamic points of varied types, spin-phonon interplay, and others.
