Researchers make a surprising discovery: Magnetism in a common material for microelectronics

Phys.org  May 15, 2024 Nickel monosilicide (NiSi) is widely used to connect transistors in semiconductor circuits. Earlier theoretical calculations had incorrectly predicted that NiSi was not magnetic. As a result, researchers had never fully explored magnetism in NiSi. An international team of researchers (USA – University of Missouri, Oak Ridge National Laboratory, Austria, Poland) showed that NiSi metal could provide suitable new platform. The study showed high-temperature antiferromagnetism in single-crystal NiSi with Néel temperature. Antiferromagnetic order in NiSi was accompanied by non-centrosymmetric magnetic character with small ferromagnetic component in the a–c plane. It was found that NiSi manifests distinct magnetic […]
