Publikováno v: Scientific Reports, Vol 8, Iss 1, Pp 1-13 (2018)

Abstract By the fabrication of periodically arranged nanomagnetic systems it is possible to engineer novel physical properties by realizing artificial lattice geometries that are not accessible via natural crystallization or chemical synthesis. This

We study the mutual coupling of spin fluctuations and lattice vibrations in paramagnetic CrN by combining atomistic spin dynamics and ab initio molecular dynamics. The two degrees of freedom are dynamically coupled leading to non-adiabatic effects. T

A Fast Method for Calculating Magnetic Hysteresis Loops

Autor: Christian Schröder, Irina Stockem

Publikováno v: IEEE Transactions on Magnetics. 51:1-4

Calculating magnetic hysteresis loops by means of classical spin dynamic methods is a computationally challenging task. To reduce the computing time, we have developed a method that divides the complete hysteresis cycle into intervals. These interval

Experimental and theoretical investigation of the magnetization dynamics of an artificial square spin ice cluster

Autor: Jens Müller, Michael Huth, Irina Stockem, Merlin Pohlit, Christian Schröder, Fabrizio Porrati

Publikováno v: Journal of Applied Physics. 120:142103

We study the magnetization dynamics of a spin ice cluster which is a building block of an artificial square spin ice fabricated by focused electron-beam-induced deposition both experimentally and theoretically. The spin ice cluster is composed of twe
