Green function theory versus Quantum Monte Carlo calculations for thin magnetic films
S. Henning, F. Koermann, J. Kienert +2
In this work we compare numerically exact Quantum Monte Carlo (QMC) calculations and Green function theory (GFT) calculations of thin ferromagnetic films including second order ani…
Curie temperature of Kondo lattice films with finite itinerant charge carrier density
Jochen Kienert, Wolfgang Nolting
We present a model study of ferromagnetic films consisting of free Bloch electrons coupled to localized moments (Kondo lattice films). By mapping the local interaction onto an effe…
Spin wave excitations: The main source of the temperature dependence of Interlayer exchange coupling in nanostructures
S. Schwieger, J. Kienert, K. Lenz +3
Quantum mechanical calculations based on an extended Heisenberg model are compared with ferromagnetic resonance (FMR) experiments on prototype trilayer systems Ni_7/Cu_n/Co_2/Cu(00…
Mechanism of temperature dependence of the magnetic anisotropy energy in ultrathin Cobalt and Nickel films
J. Kienert, S. Schwieger, K. Lenz +3
Temperature dependent FMR-measurements of Ni and Co films are analysed using a microscopic theory for ultrathin metallic systems. The mechanism governing the temperature dependence…
A new type of temperature driven reorientation transition in magnetic thin films
F. Koermann, S. Schwieger, J. Kienert +1
We present a new type of temperature driven spin reorientation transition (SRT) in thin films. It can occur when the lattice and the shape anisotropy favor different easy direction…
Magnetic phase diagram of the Kondo lattice model with quantum localized spins
J. Kienert, W. Nolting
The magnetic phase diagram of the ferromagnetic Kondo lattice model is determined at T=0 in 1D, 2D, and 3D for various magnitudes of the quantum mechanical localized spins ranging…
