Quantum material research advances room-temperature and magnetic capabilities

Researchers are making significant strides in overcoming the limitations of quantum materials, which typically require extreme cryogenic cooling to function.

At the City College of New York, scientists have detailed a path for developing quantum materials using atomically thin van der Waals magnetic semiconductors, such as chromium triiodide and nickel phosphorus trisulfide. By utilizing materials where light-generated excitons interact directly with magnetic ripples called magnons, researchers can link optical signals to magnetic dynamics. This intrinsic connection allows for the manipulation of magnetic states through light polarization, potentially enabling new data storage and optoelectronic technologies.

In a separate development, physicists at Louisiana State University have engineered an artificial gold crystal capable of operating at room temperature. By using focused ion beams to cut hundreds of microscopic slits into a thin layer of gold, the team created a structure of
