Ferromagnetism at 230 K found in diluted magnetic semiconductor
Beijing, China (SPX) Jul 11, 2014
Diluted magnetic semiconductors (DMS) have received much attention due to their potential application in spintronics, or the storage and transfer of information by using an electron's spin state, its magnetic moment and its charge. In typical systems based on III-V semiconductors, such as (Ga,Mn)As, (In,Mn)As or (Ga,Mn)N, substitution of divalent Mn atoms into trivalent Ga (or In) sites leads to severely limited chemical solubility, resulting in metastable specimens only available as epitaxial thi ... read more

Astronomers Bring The Third Dimension To A Doomed Star's Outburst In the middle of the 19th century, the massive binary system Eta Carinae underwent an eruption that ejected at least 10 times the sun's mass and made it the second-brightest star in the sky. Now, a ... more		VLT clears up dusty mystery The origin of cosmic dust in galaxies is still a mystery [1]. Astronomers know that supernovae may be the primary source of dust, especially in the early Universe, but it is still unclear how and wh ... more		Sierra Space clears design milestone for missile tracking satellites in SDA Tranche 2 State Department sanctions North Koreans for role in arms sales Seoul official hints at US-North Korea meeting this year		Perspective of the PandaX dark matter experiment The PandaX experiment of China, which is located in the deepest underground laboratory, has released its technical design report recently.

				Carbon monoxide predicts 'red and dead' future of gas guzzler galaxy Astronomers have studied the carbon monoxide in a galaxy over 12 billion light years from Earth and discovered that it's running out of gas, quite literally, and headed for a 'red and dead' future. ... more		Messenger and Stereo Open New Window Into Solar Processes Understanding the sun from afar isn't easy. How do you figure out what powers solar flares - the intense bursts of radiation coming from the release of magnetic energy associated with sunspots - whe ... more
