Mechanisms for exchange bias
WebMay 22, 2007 · This Letter reports the unexpected finding that a substantial exchange bias can be generated between an antiferromagnet (FeMn) with a higher ordering temperature than that of the ferromagnet (CuNi). We interpret the result in terms of a temperature-dependent competition between interfacial exchange and antiferromagnet anisotropy … Webbetween two exchange bias states with opposite polarity (bipolar modulation). We use the same structure but mod-ify the direction of LSMO magnetization with respect to the current in the channel. A reversible shift of the polarity of exchange bias through the zero applied magnetic field axis is achieved with no magnetic or electric field cooling,

WebExchange bias is a property of a coupled antiferromag-netic (AFM)–ferromagnetic (FM) system that occurs due to magnetic interface effects [1]. It is widely used in many … WebJan 11, 2024 · In the structure examined by the researchers, exchange bias manifests as a shift in the hysteresis loop of the ferromagnetic layer. This means that it can be experimentally obtained by sweeping the perpendicular magnetic field ( Hz) and then extracting the loop shift.
