Semiconductor sub-micro-/nanochannel networks by deterministic layer wrinkling
Yongfeng Mei, Dominic J. Thurmer, Francesca Cavallo +2
we demonstrate a technology "Release and bond-back of layers (REBOLA)" that exploits the deterministic wrinkling of a semiconductor layer to create well-defined and versatile nanoc…
{\it In-situ} Laser Microprocessing at the Quantum Level
Armando Rastelli, Ata Ulhaq, Suwit Kiravittaya +3
One of the biggest challenges of nanotechnology is the fabrication of nano-objects with perfectly controlled properties. Here we employ a focused laser beam both to characterize an…
Influence of strain on magnetization and magnetoelectric effect in La0.7A0.3MnO3 / PMN-PT(001) (A = Sr; Ca)
C. Thiele, K. Dorr, O. Bilani +2
We investigate the influence of a well-defined reversible biaxial strain <=0.12 % on the magnetization (M) of epitaxial ferromagnetic manganite films. M has been recorded depending…
Spin-flop transition in uniaxial antiferromagnets: magnetic phases, reorientation effects, multidomain states
A. N. Bogdanov, A. V. Zhuravlev, U. K. Roessler
The classical spin-flop is the field-driven first-order reorientation transition in easy-axis antiferromagnets. A comprehensive phenomenological theory of easy-axis antiferromagnet…
SrCu(PO): A real material realization of the 1D nearest neighbor Heisenberg chain
M. D. Johannes, J. Richter, S. -L. Drechsler +1
We present evidence that crystalline Sr_2Cu(PO_4)_2 is a nearly perfect one-dimensional (1D) spin-1/2 anti-ferromagnetic Heisenberg model (AHM) chain compound with nearest neighbor…
Instabilities of switching processes in synthetic antiferromagnets
A. N. Bogdanov, U. K. Roessler
It is shown that magnetic states and field-driven reorientation transitions in synthetic antiferromagnets crucially depend on contributions of higher-order anisotropies. A phenomen…
