I’m pleased to have contributed to a recent perspective article exploring the progress and ongoing challenges in understanding exchange bias in van der Waals heterostructures. While exchange bias has played a key role in advancing spintronics and has been extensively investigated in conventional thin-film heterostructures, many aspects of its underlying mechanisms remain elusive. In this perspective article, we highlight why van der Waals heterostructures offer a compelling platform for studying exchange bias. In particular, we discuss how subtle interfacial effects between antiferromagnetic and ferromagnetic layers can give rise to fascinating variations in both the strength and polarity of the exchange bias. A sincere thank you to all collaborators—especially Prof. Mathias Kläui for his guidance and support, Aditya Kumar for his proactive efforts throughout the project, and Sadeed Hameed and Xinran Wang for their valuable contributions. I look forward to seeing how this field continues to evolve. #ExchangeBias #Spintronics #2DMaterials Newton by Cell Press #KläuiLab
