On the Antiferromagnetic$\unicode{x2013}$Ferromagnetic Phase Transition in Pinwheel Artificial Spin Ice

Autor: Strømberg, Anders, Digernes, Einar, Chopdekar, Rajesh Vilas, Grepstad, Jostein, Folven, Erik

Nanopatterned magnetic thin films offer a platform for exploration of tailored magnetic properties such as emergent long-range order. A prominent example is artificial spin ice (ASI), where an arrangement of nanoscale magnetic elements, acting as mac

Effects of substrate annealing on the gold-catalyzed growth of ZnO nanostructures

Autor: Skåre Daniel, Ladam Cecile, Weigand Christian, Grepstad Jostein, Weman Helge

Publikováno v: Nanoscale Research Letters, Vol 6, Iss 1, p 566 (2011)

Abstract The effects of thermal substrate pretreatment on the growth of Au-catalyzed ZnO nanostructures by pulsed laser deposition are investigated. C-plane sapphire substrates are annealed prior to deposition of a thin Au layer. Subsequent ZnO growt

Using soft x-ray spectromicroscopy, we investigate the magnetic domain structure in embedded nanomagnets defined in La$_{0.7}$Sr$_{0.3}$MnO$_3$ thin films and LaFeO$_3$/La$_{0.7}$Sr$_{0.3}$MnO$_3$ bilayers. We find that shape-controlled antiferromagn
