An intermediate state between the kagome-ice and the fully polarized state in Dy2Ti2O7
(Instituto de Física de Líquidos y Sistemas Biológicos, 2015-06)
Dy2Ti2O7 is at present the cleanest example of a spin-ice material. Previous theoretical and experimental work on the first-order transition between the kagome-ice and the fully polarized state has been taken as a validation ...
Um modelo de excitações interagentes para descrição de gelos de spins artificiais
(Universidade Federal de Minas GeraisUFMG, 2018-05-04)
Artificial spin ice is a class of two dimensional nanomagnetic systems fabricated by litography. They are initially proposed to resemble the crystalline spin ice, allowing the theoretical and experimental investigation of ...
Entropy as a function of magnetisation for a 2D spin-ice model exhibiting a Kasteleyn transition
(IOP Publishing, 2018-08)
We present a combined analytical and numerical study of the entropy as a function of magnetization for an orientable 2D spin-ice model that exhibits a Kasteleyn transition. The model that we use is related to the well known ...
Pinning of ferromagnetic domains in interconnected pentagonal spin ice lattices
(2019)
The magnetization reversal process of interconnected pentagonal spin ice systems was investigated using micromagnetic simulations and experimental measurements. Five different systems were investigated, beginning with the ...
