source:energyindustryreviewOne of the most amazing phenomena of nature is the manifestation of magnetism in some materials. Permanent magnets are known since ancient times. Before the great discoveries in the field of electricity, permanent magnets were actively used by physicians. Over time, people learned to create artificial magnets by placing iron alloy products in magnetic fields. Permanent magnets are frequently used in industry, in various fields, such as electrical engineering, computer technologies, transportation, navigation, medicine, biology, astronomy etc. The main application of ...

Source:DOE/SLAC National Accelerator LaboratoryA new study shows that nickel oxide superconductors, which conduct electricity with no loss at higher temperatures than conventional superconductors do, contain a type of quantum matter called charge density waves, or CDWs, that can accompany superconductivity.The presence of CDWs shows that these recently discovered materials, also known as nickelates, are capable of forming correlated states -- 'electron soups' that can host a variety of quantum phases, including superconductivity, researchers from the Department of Energy's SLAC Nat...

source:azoopticsPulsed lasers, a crucial component of the laser industry, are continuously developed to produce higher repetition frequencies and greater intensity. Recently published research findings from the Shanghai Institute of Optics and Fine Mechanics at the Chinese Academy of Sciences exhibit a crystal with promising pulsed laser properties. Research efforts led by the group of Professor Yin Hang and published in Optics & Laser Technology have demonstrated the first laser operation of perovskite oxide LaAlO3 doped with 0.1 at% Nd ions and 0.2 at% Th (Nd,Th:LaAlO3).What are Pulsed L...
