The magnetic properties of oxides with perovskite, corundum, ilmenite and amorphous structures have been compiled in subvolume 27F. Part 27F2, published in 1994, presents magnetic data on perovskite-type layered cuprates which were discovered to show superconductivity with critical temperatures above 40 K (high-T_c superconductors). The present volume 27F2S is an update and extension of 27F2 with more precise data on high quality single crystals and some new effects and phenomena, covering the literature of the period 1991-2000.
