Exchange Coupling in Magnetic Multilayers Grown on Iron Whiskers (invited)
Meaningful tests of theoretical predictions of magnetic multilayer properties require the fabrication of multilayers with nearly the same atomic scale precision as the theoretical models. Multilayers grown epitaxially on single crystal Fe whisker substrates come very close to this ideal standard. We have investigated the growth, magnetic structure, and exchange coupling of Fe/(Ag, Au, Cr, Mn, V...
متن کاملAnomalous bias factors of dislocations in bcc iron
Dislocation bias factors in bcc Fe have been calculated based on atomistic interaction energy maps on three kinds of dislocations, namely the a0/2〈111〉{110} screw, a0/2〈111〉{110} and a0〈100〉{001} edge dislocations. The results show that the dislocation bias is higher for the a0/2〈111〉 edge dislocation than for the a0〈100〉 edge dislocation, even though the latter possesses a larger Burgers vecto...
متن کاملSmall-Angle Neutron Scattering Study of Dislocations in Deformed Single-Crystal Copper
Small-angle neutron scattering measurements of deformed single-crystal copper have been performed over a wave-vector transfer range of 0.0655 <__ Q < 1.32 nm l . The measurements included four samples deformed in compression at room temperature along the [110] direction to 6.8, 15.6, 35.0 and 54.3% reduction in thickness and an undeformed reference sample. The response of the reference sample f...
متن کاملVibrational density of states measurement of hydrogen trapped at dislocations in deformed PdH0.0008
The vibrational density of states DOS of hydrogen trapped at dislocations in deformed PdH0.0008 has been measured at 4 and 295 K with incoherent inelastic neutron scattering. The vibrational DOS at 4 K exhibits features characteristic of the low-temperature -Pd hydride phase while the characteristic peak in the 295 K DOS corresponds to the solid-solution -Pd phase. This is evidence of a → trans...
