Laser pulses triple transition temperature for ferromagnetism in YTiO3

Scientists successfully introduce ferromagnetism into bismuth ferrite at room temperature through dual-cation substitution, enabling potential use in low-power memory devices. Negative thermal expansion is also observed, which could help solve problems caused by thermal expansion in electronic components.

Researchers have developed Cr³⁺-doped InP/ZnS quantum dots that exhibit pure blue emission and room-temperature ferromagnetism. The dual-functional QDs are achieved through a hot injection method, which effectively passivates surface defects and suppresses non-radiative recombination.

Researchers mapped key aspects of electron pulses that can generate laser-like X-ray pulses, improving access to XFELs. The technique enables studying molecule behavior in detail and advancing fields like chemistry and medicine.

A team of scientists observed Jahn–Teller polarons in cobalt oxide crystals activated by tailored laser pulses. The study reveals the material's structural, electrical, and magnetic properties can be engineered using ultrafast laser pulses.

Researchers at Hefei Institutes of Physical Science achieved record pulse energies with a laser diode-pumped Er,Pr:GYAP laser operating at 2.7 μm. The crystal helps improve laser performance, expanding the emission range and reducing energy losses. The laser produced high-energy pulses with Q-switched operation.

Researchers at TU Wien have developed a new method to generate extremely short, powerful ion pulses for controlled analysis of material surfaces. These pulses can be used to observe chemical processes in real-time, providing insights into surface physics and chemistry on a picosecond time scale.
