[en] Results on high-magnetic-field studies of layer structure dichalcogenides and 3d ferromagnetic metals are reported. These results have contributed to a further understanding of the electronic structure in these materials including charge density wave transitions, anisotropic superconductivity, band structure, Fermi surface and magnetic phenomena. In the case of charge density wave (CDW) materials, the effects of the CDW transitions were measured directly through the use of quantum oscillatory transport and Raman scattering in highly perfect crystals. Modifications of this CDW structure by addition of impurities and new electronic characteristics introduced in this way were measured and analyzed. In the 3d ferromagnetic metals data in the range 150 to 230 kG indicate new behavior in the magnetotransport which will help in analyzing the details of the complex Fermi surfaces in these materials. The program on electron tunneling produced new results on using inelastic electron tunneling to determine the orientation of surface-adsorbed molecules, interactions of molecules with surfaces, and electron--phonon coupling in molecules. Further development with a variety of substrate surfaces is underway, and the technique should be useful in a wide range of surface studies where real rather dirty conditions prevail. A variety of applications where a high sensitivity vibrational spectrum can provide useful information are illustrated in brief descriptions of experiments. Detailed reports appear in various publications. 5 figures
