Journal Article
Atxitia, U., Ostler, T. A., Chantrell, R. W., & Chubykalo-Fesenko, O. (2015). Optimal electron, phonon, and magnetic characteristics for low energy thermally induced magnetization switching. Applied physics letters, 107(19), Article 192402. https://doi.org/10.1063/1.4935416

Using large-scale computer simulations, we thoroughly study the minimum energy required to thermally induced magnetization switching (TIMS) after the application of a femtosecond heat pulse in transition metal-rare earth ferrimagnetic alloys. We find... Read More about Optimal electron, phonon, and magnetic characteristics for low energy thermally induced magnetization switching.

The Landau-Lifshitz equation in atomistic models (2015)
Journal Article
Ellis, M. O., Evans, R. F., Ostler, T. A., Barker, J., Atxitia, U., Chubykalo-Fesenko, O., & Chantrell, R. W. (2015). The Landau-Lifshitz equation in atomistic models. Low Temperature Physics, 41(9), 705-712. https://doi.org/10.1063/1.4930971

The Landau-Lifshitz (LL) equation, originally proposed at the macrospin level, is increasingly used in Atomistic Spin Dynamic (ASD) models. These models are based on a spin Hamiltonian featuring atomic spins of fixed length, with the exchange introdu... Read More about The Landau-Lifshitz equation in atomistic models.

Ultrafast and Distinct Spin Dynamics in Magnetic Alloys (2015)
Journal Article
Radu, I., Stamm, C., Eschenlohr, A., Radu, F., Abrudan, R., Vahaplar, K., …Rasing, T. (2015). Ultrafast and Distinct Spin Dynamics in Magnetic Alloys. SPIN, 5(3), Article 1550004. https://doi.org/10.1142/S2010324715500046

Controlling magnetic order on ultrashort timescales is crucial for engineering the next-generation magnetic devices that combine ultrafast data processing with ultrahigh-density data storage. An appealing scenario in this context is the use of femtos... Read More about Ultrafast and Distinct Spin Dynamics in Magnetic Alloys.

Strain Induced Vortex Core Switching in Planar Magnetostrictive Nanostructures (2015)
Journal Article
Ostler, T. A., Cuadrado, R., Chantrell, R. W., Rushforth, A. W., & Cavill, S. A. (2015). Strain Induced Vortex Core Switching in Planar Magnetostrictive Nanostructures. Physical review letters, 115(6), Article 067202. https://doi.org/10.1103/PhysRevLett.115.067202

The dynamics of magnetic vortex cores is of great interest because the gyrotropic mode has applications in spin torque driven magnetic microwave oscillators, and also provides a means to flip the direction of the core for use in magnetic storage devi...
