We report our recent progress in high-pressure magnetization and nuclear magnetic resonance (NMR) measurement techniques up to around 10 GPa. We developed two types of the opposed-type anvil cells for very precise magnetization measurement of quantum magnetism, and single-crystal NMR experiment for strongly correlated electron systems including superconductor. These have been established partly by using newly developed conical-shape gasket, giving rise to significantly larger sample volume. For practical NMR experiment, sealing method of liquids, electrodes, and optical fiber through a conical hole inside an anvil is also developed. To demonstrate those performance, high-pressure experiment of MnP is shown.
