A new study shows that trapping light inside magnetic materials may dramatically enhance their intrinsic properties. Strong optical responses of magnets are important for the development of magnetic lasers and magneto-optical memory devices, as well as for emerging quantum transduction applications.
A new study led by Vinod M. Menon and his group at the City College of New York shows that trapping light inside magnetic materials may dramatically enhance their intrinsic properties. Strong optical responses of magnets are important for the development of magnetic lasers and magneto-optical memory devices, as well as for emerging quantum transduction applications.
"Ordinarily, light does not respond so strongly to magnetism," said Menon."This is why technological applications based on magneto-optic effects often require the implementation of sensitive optical detection schemes." On how the advances can benefit ordinary people, study co-author Jiamin Quan said:"Technological applications of magnetic materials today are mostly related to magneto-electric phenomena. Given such strong interactions between magnetism and light, we can now hope to one day create magnetic lasers and may reconsider old concepts of optically controlled magnetic memory." Rezlind Bushati, a graduate student in the Menon group, also contributed to the experimental work.
The study conducted in close collaboration with Andrea Alù and his group at CUNY Advanced Science Research Center is the result of a major international collaboration. Experiments conducted at CCNY and ASRC were complemented by measurements taken at the University of Washington in the group of Prof. Xiaodong Xu by Dr. Geoffrey Diederich. Theoretical support was provided by Dr. Akashdeep Kamra and Prof. Francisco J. Garcia-Vidal from the Universidad Autónoma de Madrid and Dr.

Evolving elegance: Scientists connect beauty and safeguarding in ammonoid shells -- ScienceDailyWith 350 million years of evolution culminating in almost two centuries of scientific discourse, a new hypothesis emerges. Researchers propose a new explanation for why ammonoids evolved a highly elaborate, fractal-like geometry within their shells. Their analysis shows that the increasing complexity of shell structures provided a distinct advantage by offering improved protection against predators.
