Abstract

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.

Highlights

A separate place in the physics of films is occupied by films of magnetically ordered substances (Ni, Fe, Co, and magnetic alloys)
Oxidation of nickel films occurs through the transfer of electrons, nickel cations, and oxygen anions through the film
According to the analysis of this study, it was found that Ni films with a thickness of 50 nm are almost completely oxidized at an annealing temperature of 700 ° C

Summary

Introduction

A separate place in the physics of films is occupied by films of magnetically ordered substances (Ni, Fe, Co, and magnetic alloys) This is due to the fact that they allow us to solve a number of fundamental problems for “two-dimensional magnetism”, as well as the fact that they have a number of specific magnetic properties: a specific domain structure and the associated magnetic anisotropy, “magnetization ripple”, etc. Ni is an excellent candidate for studying magnetic properties depending on thickness, because has the lowest Curie point (TC = 631 K) in the series of ferromagnetic metals (Fe, Co); over the entire range of thicknesses and temperatures, Ni, unlike Fe and Co, has no polymorphic transitions, while retaining the fcc lattice responsible for ferromagnetism. In Ni films, both in the bulk state and in the film [8], they are the simplest, as it were “model”, to study their properties, in addition, to date, the electrical and especially galvanomagnetic properties of the films have been little studied
