Megagauss magnetization measurements

Techniques of magnetization measurements in ultrahigh magnetic fields are d iscussed. A high rate of magnetic field growth and electromagnetic noises i mpose severe restriction on an experimental set-up. It is shown that a magn etization step (at a metamagnetic transition) and the conductivity can be e stimated from magnetization data. Magnetic oscillations are also observable in ultrahigh magnetic fields. Experimental results on FeSi, high-temperatu re superconductors, rare-earth intermetallic compounds, and high-spin molec ular clusters are briefly reviewed. (C) 2001 Elsevier Science B.V.
