Optical spin defect pairs in cubic boron nitride
Josiah E. Hsi, Islay O. Robertson, Abhijit Biswas +9
Room-temperature optically active solid-state spin defects are widely known to be useful in quantum sensing applications, however, only a select range of materials have been found…
Omnidirectional magnetic imaging of magnetic anisotropy and phase transitions
Alexander J Healey, Kaijian Xing, Weiyao Zhao +7
Micron scale imaging of magnetic fields is an important tool for understanding the evolution of magnetism through phase transitions and as a result of interactions inside of hetero…
Imaging magnetic switching in orthogonally twisted stacks of a van der Waals antiferromagnet
Alexander J Healey, Cheng Tan, Boris Gross +9
Stacking van der Waals magnets holds promise for creating new hybrid materials with properties that do not exist in bulk materials. Here we investigate orthogonally twisted stacks…
Violet to near-infrared optical addressing of spin pairs in hexagonal boron nitride
Priya Singh, Islay O. Robertson, Sam C. Scholten +9
Optically addressable solid-state spins are an important platform for practical quantum technologies. Van der Waals material hexagonal boron nitride (hBN) is a promising host as it…
Towards high spatial resolution magnetic imaging with a compact practical quantum diamond microscope
Kevin J. Rietwyk, Alex Shaji, Islay O. Robertson +6
Widefield quantum diamond microscopy is a powerful technique for imaging magnetic fields with high sensitivity and spatial resolution. However, current methods to approach the ulti…
A charge transfer mechanism for optically addressable solid-state spin pairs
Islay O. Robertson, Benjamin Whitefield, Sam C. Scholten +9
Optically detected magnetic resonance (ODMR) with no resolvable zero-field splitting has been observed from emitters in hexagonal boron nitride across a broad range of wavelengths,…
