“…As stated in the introduction, other studies found interdiffusion to be negligible below 200°C. 13,16,[18][19][20][21] However, this also implies that the heterostructures are not uniform across the whole surface and/or across the whole depth. In order to observe several peaks, part of the heterostructure must have a slightly different sequence of layers, but still be uniform and crystalline enough to give a diffraction peak.…”

“…[7][8][9][10] Heterostructures built from alternating layers of deposited Ag and Pd have been studied experimentally in the past few years using x-ray diffraction (XRD), synchrotron-radiation induced photoelectron spectroscopy (SR-PES), atomic force microscopy, scanning tunneling microscopy (STM) and many other techniques. [11][12][13][14][15][16][17][18][19][20][21] At room temperature Ag and Pd have been described as growing layer by layer on each other. Standard properties are still controversial, as both metals have been observed to grow on the other with their own lattice parameter as well as pseudo-morphically.…”

“…14,15,22 In superlattices, root-mean-squared interface roughness can be lowered to about 1 atomic layer 21 but interdiffusion occurs above 200°C. 13,16,[18][19][20][21] Much is known about thick multilayers of Ag and Pd, about the epitaxial growth of the metals on each other, and about their interdiffusion and alloy formation. The Ag/ Pd system looks like the ideal superlattice: perfectly layered when grown at room temperature and without any interdiffusion.…”

The electronic structure of silver-palladium heterostructures is investigated, both experimentally and through ab initio calculations. Synchrotron-radiation induced photoelectron spectroscopy characterizations of the work function and the valence band structure are compared to and explained by calculations of slab and bulk heterostructures. Work functions and equilibrium geometries are shown to be in agreement with synchrotronradiation induced photoelectron spectroscopy, x-ray diffraction and scanning tunneling microscopy measurements. Further insight into the differing behavior of the two terminating metal surfaces is extracted from the calculations.

“…The microstructure of Co-Pd systems has been studied for a better understanding of the structure-property relation [3][4][5] and the noise is thought to come from the strong intergranular exchange coupling [10,11]. The ferromagnetism is considered to be the result of interfacial effects [12,13].…”

Various perpendicular ferromagnetic superlattices of the Co/Pd system were made to tune magnetic properties and recording performance, dependent on factors like sputtering pressure, sputtering gas, bilayer number, sublayer thickness, deposition temperature, annealing, type of seed layer, seed layer thickness and grain size, and distribution. Structural analysis by x-ray diffraction and TEM shows columnar growth and orthorhombic (tetragonal) microcrystalline packing that accounts for the ferromagnetic properties by polarization of the atoms during deposition, in contrast to the non-ferromagnetic state of the fcc crystal structure superlattice after high-temperature annealing. The M-H loop is described by a recently developed analytical hysteresis model and the result is substantiated by the structural analysis of grain sizes from multiple magnetic phases.
