Abstract

Magnetostrictive materials are of significant interest due to their potential applications in sensors, actuators, and energy converters. For magnetostrictive materials, different preparation processes are crucial to the quality of their magnetostrictive effect. In this work, Ni50Mn27Ga23 alloys in as-cast, directionally solidified, and melt-spun states were synthesized, and their structural, magnetic, and magnetostrictive properties were investigated. The results reveal that grain size and growth orientation are strongly influenced by the preparation method. Smaller grain sizes and increased grain boundaries hinder domain reorientation under external fields, leading to reduced magnetostriction and higher saturation fields. Growth orientation also affects saturation, further impacting both magnetic and magnetostrictive properties. This work provides valuable insights into the structure–magnetostriction relationship, offering guidance for developing excellent magnetostrictive materials.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
