Quantum versus classical nature of a low-temperature magnetic phase transition in TbAl(BO)
T. Zajarniuk, A. Szewczyk, P. Wisniewski +8
Specific heat, , of a TbAl(BO) crystal was studied for 50 mK 300 K, with emphasis on K, where a phase transition was found at K. Nuclear, n…
Topological charge scaling at a quantum phase transition
Piotr Tomczak
We reexamine the Kosterlitz-Thouless phase transition in the ground state of an antiferromagnetic spin- Heisenberg chain with nearest and next-nearest-ne…
How to accurately determine a saturation magnetization of the sample in a ferromagnetic resonance experiment?
P. Tomczak, H. Puszkarski
The phenomenon of ferromagnetic resonance (FMR) is still being exploited for determining the magnetocrystalline anisotropy constants of magnetic materials. We show that one can als…
Ferromagnetic resonance in thin films - cross-validation analysis of numerical solutions of Smit-Beljers equation. Application to GaMnAs
Piotr Tomczak, Henryk Puszkarski
(Dated: August 3, 2018) The new method of numerical analysis of experimental ferromagnetic resonance (FMR) spectra in thin films is developed and applied to (Ga,Mn)As thin films. S…
A Monte Carlo study of critical properties of strongly diluted magnetic semiconductor (Ga,Mn)As
P. Tomczak, H. T. Diep, P. Jabłoński +1
Within a Monte Carlo technique we examine critical properties of diluted bulk magnetic semiconductor (Ga,Mn)As modeled by a strongly diluted ferromagnetic Heisenberg spin-$\frac{5}…
On the existence conditions of surface spin wave modes in (Ga,Mn)As thin films
H. Puszkarski, P. Tomczak
Spin-wave resonance (SWR) is a newly emerged method for studying surface magnetic anisotropy and surface spin-wave modes (SSWMs) in (Ga,Mn)As thin films. The existence of SSWMs in…
