| Abstract | The hyperfine field B/sub hf/ at positive muon ( mu /sup +/) in iron and nickel was previously found. Exhibits marked deviations from the bulk magnetization as a function of temperature. For substitutional impurities in Fe and Ni matrices the volume dependence of B/sub hf/ has been considered as a possible reason for such deviations. Therefore the authors have measured at CERN the local magnetic field at mu /sup +/, B/sub mu /, in high purity polycrystalline Fe and Ni samples at room temperature and at pressures up to 7 kbar by the positive muon spin rotation ( mu /sup +/ SR) technique. To their knowledge, this is the first mu /sup +/SR experiment performed under hydrostatic pressure. The authors observe a linear pressure dependence for both samples but slopes are of opposite signs.
