Extrinsic control of the exchange bias
نویسندگان
چکیده
A new control mechanism for the exchange bias effect in magnetic heterostructures is proposed. It takes advantage of the magnetoelectric effect which takes place in the antiferromagnetic pinning layer. In contrast with the pioneering AC measurements of the magnetoelectric effect, we investigate the magnetic response of the prototypical magnetoelectric compound Cr2O3 on static electric fields. The linear dependence of the magnetic moment on the applied axial electric field and the temperature dependence of the corresponding slopes aJ are measured by DC SQUID magnetometry. The contribution of the field-induced surface magnetization and its impact on the exchange bias effect is estimated. r 2004 Elsevier B.V. All rights reserved. PACS: 75.80.þq; 75.70. i; 75.47. m

Exchange bias driven by the Dzyaloshinskii-Moriya interaction and ferroelectric polarization at G-type antiferromagnetic perovskite interfaces.
Exchange bias is usually rationalized invoking spin pinning effects caused by uncompensated antiferromagnetic interfaces. However, for compensated antiferromagnets other extrinsic factors, such as interface roughness or spin canting, have to be considered to produce a small uncompensation. As an alternative, here we propose two (related) possible mechanisms, driven by the intrinsic Dzyaloshinsk...
متن کاملA Comparison of the Effectiveness of Cognitive Bias Modification in Real and Placebo Conditions on Attentional Bias and Approach Bias in Opium Abusers
Background & Aim: Inability to control drug use is considered a core aspect of drug dependency. Part of this inability is due to cognitive biases resulting from individuals’ constant usage of drugs. The aim of the present study was to compare the effectiveness of cognitive bias modification in real and placebo conditions on attentional bias and approach bias in opium abusers. Methods: This stud...

متن کاملDesigning a Model and Explaining Persuasion Techniques in Disclosure Financial Reports by Companies with Job Acquisition Incentives Bias CEO
Increasing the regulatory environment and expanding the scope of the regulatory standards for financial reporting has, over the past few years, reduced the cost of representation and information asymmetry and increased the level of corporate disclosure of corporate financial statements. But one of the endogenous dimensions of quality that prevents the disclosure of financial statements is a mat...

The purpose of this paper is to study the main determinants of the bilateral real exchange rates for major oil exporting countries vis-à-vis the US dollar. Taking into account the impact of the real oil prices on real exchange rates, it may be observed that oil prices play a significant part in determining the terms of trade. In addition to the real oil price, two other fundamental factors that...
