Quantum sensing applications

Spinwaves

Spin wave devices, such as spin wave logic gates and spintronic filters, are increasingly attracting attention for their potential in next-generation computing and data processing. Local imaging of spin waves has been difficult, but Scanning NV magnetometry now offers precise measurement capabilities. This advancement significantly enhances the field of magnonics, opening new avenues for research and practical applications
