Efficacité et rémanence de l'amitraz (Taktic R) sur les adultes de Hyalomma dromedarii chez le dromadaire : preliminary study

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 1994
L'amitraz (concentré émulsifiable à 12,5 %) a été testé comme moyen de contrôle de Hyalomma dromedarii sur dromadaire dans un troupeau de chamelles laitières de la périphérie de Nouakchott (Mauritanie) à la concentration de 0,025 % de matière active.

Magnetic record associated with tree ring density: Possible climate proxy

open access: yesGeochemical Transactions, 2007
A magnetic signature of tree rings was tested as a potential paleo-climatic indicator. We examined wood from sequoia tree, located in Mountain Home State Forest, California, whose tree ring record spans over the period 600 – 1700 A.D. We measured low and

In-plane strain control of the magnetic remanence and cation-charge redistribution in CoFe 2 O 4 thin film grown on a piezoelectric substrate

open access: yes, 2010
Strain engineering of the magnetic property is an important subject in the study of multiferroic materials. Here we propose a multiferroic bilayer structure in which the magnetic remanence is controlled by the in-plane strain of the top CFO $({\text{CoFe}

Phase evolution, microstructure, and improved magnetic properties for off-stoichiometric SmFe12-based alloys

open access: yesJournal of Materials Research and Technology
Low rare earth content and high intrinsic magnetic properties make SmFe12-based permanent magnets a potential candidate for NdFeB-based magnets in medium to high temperature environments.

Magnetic stripe domains of [Pt/Co/Cu]10 multilayer near spin reorientation transition

open access: yesAIP Advances, 2016
The dependence of magnetic anisotropy, magnetic domain patterns and magnetization reversal processes in [Pt/Co(tCo)/Cu]10 film stack epitaxied on Cu (111) substrate have been studied as a function of the Co layer thickness tCo, by magneto-optic polar ...

Pressure demagnetization: Electromagnetism meets thermodynamics

open access: yesAIP Advances
By pressure demagnetization, take iron as an example, we mean either that, given an external magnetic field under a certain temperature, the magnetization becomes weaker as the pressure increases, which can be referred to as pressure demagnetization ...
