Magnetic collapse and insulator-metal transitions in simple and complex 3<Emphasis Type="Italic">d</Emphasis>-metal oxides at high pressures

The latest results of experimental study of the effect of high pressure on the magnetic and crystal structures, electronic and spin states, and transport properties of some 3d-metal oxides with different crystal structures are reported. Along with the X-ray diffraction, optical absorption spectroscopy, and Raman spectroscopy, direct resistivity measurements have been performed and several techniques based on synchrotron radiation were used to carry out high-pressure experiments in diamond anvil cells.
