Magnetotransport properties and the Fermi surface of single crystal VB2

ABSTRACTThe role of the interlayer Fermi surface in driving oscillatory exchange coupling of ferromagnetic layers has been critically tested in a series of MBE-grown coherent epitaxial sandwiches prepared on single-crystal substrates. The wedge-shaped Cu (or Cu-based) interlayers have been modified in a number of different ways, achieving orientational, compositional and structural alteration of the Cu Fermi surface. Observed phenomena include multiperiodic coupling oscillations in both the ferromagnetically and antiferromagnetically coupled regions of (lOO) -oriented Co/Cu/Co samples, extended oscillatory periods across CuNi alloy interlayers, and extremely short-period oscillations in a bcc (100) Fe/Cu/Fe system. These phenomena are straightforwardly explained in terms of calculated Fermi surface variations.

Crystal Films

In this work we studied the anisotropy of the transverse magnetoresistance of single-crystal nickel films. The measurements were carried out on samples whose surface plane coincided with the [001] cavity. Studies of magnetoresistance in a monocrystalline nickel film showed tensile stresses acting on it from the side of magnesium oxide. The modification of the magnetization anisatropy of the film on the substrates as compared with the free sample is apparently associated with a change in the shape of the Fermi surface of the carriers.

First Time

The absolute amplitudes of quantum oscillations in magnetostriction and the elastic constant, c11, have been measured simultaneously, for the first time, in a single crystal sample of tungsten. They are combined to give the strain dependence of the Fermi surface cross sections normal to [100] of the ball and ellipsoid surfaces. Comparison with values measured in another type of uniaxial experiment and with pressure derivatives indicates that the results are consistent, and that the method is feasible, although less convenient than other possible measurements giving the same information.
